* Refactored TiledElevationCoverage construction to support WCS (#649)

Modified TiledElevationCoverage to enable construction via configuration object. This enables loose coupling between a WebCoverageService specifying the configuration, and the scene component that consumes the configuration (TiledElevationCoverage). This is the first of several changes that streamline TiledElevationCoverage construction.

This change knowingly breaks backward compatibility. The class TiledElevationCoverage is new since 0.9.0. While we could argue that it should be possible to port 0.9.0 ElevationModel construction to TiledElevationCoverage, as the constructors currently appear very similar, they are fundamentally different. Additionally, the opportunity to improve the elevation coverage interface oughtweighs the benefit we might gain by making it easy to port old ElevationModel code to TiledElevationCoverage.

Relates to #486

* Simplify TiledElevationCoverage tile management (#650)

This change simplifies TiledElevationCoverage construction by removing the unnecessary cachePath configuration parameter. We could limit the scope of this change by assigning any string to cachePath and leaving TiledElevationCoverage's implementation unchanged. However, TiledElevationCoverage has significant unnecessary complexity that creates and tracks unique elevation tile keys based on the notion that cachePath is necessary. Elevation tiles and elevation images are are stored in an cache unique to each instance of TiledElevationCoverage (rather than a shared cache). Given that, there is no need to generate globally unique cache keys, which is the only purpose served by cachePath. It is enough to use Tile.tileKey, which can uniquely identify each tile in the coverage's tile cache and image cache.

This iteration removes the unnecessary ElevationTile class and replaces its usages with Tile. Additionally, this iteration removes the imagePath properties that derive from cachePath, replacing them with usage of Tile.tileKey or in-place generation of a tile key string (when a tile instance is not available). Given the size of this change, i have left cachePath intact, with the intent to remove it and its usages in the various TiledElevationCoverage implementations in the next iteration.

* Removed usage of TiledElevationCoverage's cachePath (#653)

- This change follows #650 to remove the usage of TiledElevationCoverage cachePath.
- Relates to #486

* Automated TiledElevationCoverage LevelSet configuration (#654)

The LevelSet parameters required during TiledElevationCoverage construction are much better as an implementation detail. The caller has already supplied the minimum necessary information needed to configure a LevelSet: sector and resolution. Requiring the caller to specify a level count is unnecessary and potentially dangerous. Level count is trivial to derive from resolution, but its easy for an uniformed caller to specify a level count that does not match the data. Additionally, the level zero delta and tile width/height are carefully chosen to balance operation and performance, and should not be specified by the caller. The level zero delta, tile width, and tile height are set to constant values known to work well with TiledElevationCoverage. The level count is derived from the resolution. The resultant LevelSet has a last level that either matches or exceeds the specified coverage resolution.

Note: The LevelSet defaults are left as inline constants, as TiledElevationCoverage's usage of LevelSet is temporary.

Relates to #486

* Updated the Standalone example elevation coverage (#655)

EarthRestElevationCoverage, the coverage used by Standalone.html, was out of date after recent changes to TiledElevationCoverage. Updated this coverage implementation to correctly retrieve standalone elevation tiles.

* Add elevation config property to WcsCoverage (#652)

   only reffered as "credits".

* Modified how ElevationCoverage.elevationsForGrid interprets resolution (#656)

* Modified how ElevationCoverage.elevationsForGrid interprets resolution

The function elevationsForGrid derived from the original ElevationModel, which used targetResolution to select a level in the model's tile pyramid. Since implementing composable elevations (#575), this function appears in both ElevationModel and ElevationCoverage, but serves a different purpose in each. Given that, the argument list need not be the same, and in fact should not be the same. ElevationModel needs targetResolution to let the caller influence which coverage is chosen to fulfil the request. ElevationCoverage does not need targetResolution. Allowing the caller to specify a resolution to ElevationCoverage is unnecessary and potentially dangerous. The grid itself provides an implicit resolution the coverage can use to select a level, and letting the caller override that resolution risks the caller accessing more data than can fit in memory.

* Rollback screen credit hyperlink support (#755)

* Rollback screen credit hyperlink support

- The implementation of screen credit hyperlinks causes several bugs in WebWorldWind's examples.
- Adding a ClickRecognizer and TapRecognizer to BasicWorldWindowController prevented recognizers in the examples from detecting clicks and taps.
- Additionally, applications making use of ClickRecognizer or TapRecognizer would be affected by this behavior, so we're rolling back the change until this issue can be addressed.

 - Moved the UI layer creation to the top. This is uncharacteristic
   compared with other examples, but this part broke the flow of the
   narration of the example when it was positioned in the middle. Due
   to technical necessities, the AtmosphereLayer creation is still
   in the same location, though.

   readable.

 - Added a comment regarding the animation interval.

* Convert the embedded JSZip to RequireJS for build compatibility (#770)

* Updated BlueMarble and Landsat layers to capture their full resolution (#773)

- Blue Marble's native resolution is 4.166666667E-03 deg/pixel.
- Landsat's native resolution is 1.38889E-04 deg/pixel.
- Increased BMNGLayer's maximum resolution from 5.5E-0.3 deg/pixel to 1.4E-0.3 deg/pixel.
- Increased BMNGLandsatLayer's maximum resolution from 1.7E-0.4 deg/pixel to 4.3E-0.5 deg/pixel.
- Given the modest increase in resolution, this change has no effect on runtime performance.

Closes #772

* Update README.md (#801)

* Disable Travis CI deployment in preparation for project suspension (#802)

* Update the README files's Travis CI badge (#803)

* Update WebWorldWind build dependencies (#804)

Updated the WebWorldWind npm project's build dependencies to ensure compatibility with the latest version of Node.js, Grunt, Karma, and Jasmine.

While changes like this are always worthwhile, I'm making it now to ensure that the original WebWorldWind source and its accompanying npm project will continue to operate for as long as possible after the [WorldWind project's suspension on April 5, 2019](https://worldwind.arc.nasa.gov/news/2019-03-08-suspension-notice).  Secondary goals are eliminating all npm audit warnings from old versions of libraries used to build WebWorldWind (i.e. the devDependencies) and ensuring that unit tests continue to operate.

Summary of changes:

- WebWorldWind now builds with Node.js 10.15.3 LTS and 11.12.0. The README file and the Travis CI configuration file reflect that.

- All npm devDependencies, used for building the WorldWind project, are updated to the latest version available as of this pull request.

- All npm security audit vulnerabilities are addressed.

- Subtle errors in unit tests fixed. WorldWind's geometric unit tests erroneously modified global variables, such as Location.ZERO. These values shouldn't be encoded as global variables, but solving that is out of scope here. Previous versions of Jasmine concealed this problem but these unit tests fail with Jasmine 3.x, likely due to a change in the Jasmine interpreter lifecycle between tests.

 - As per KML's 2.2 specification, if altitudeMode is not specified, it should be interpreted as CLAMP_TO_GROUND. This commit ensures this behavior.

 - Added method for validation of altitudeMode existence in KML file, imitating WWJ's KMLPlacemark behavior.

* Temporarily changed data source used in KML example to test a KML file with no altitudeMode specified

* Added KML file with no altitudeMode specified
 - Downloaded from here:
   https://opendata.hayward-ca.gov/datasets/hayward-general-plan-land-use?geometry=-122.322%2C37.590%2C-121.845%2C37.685
