2.0.0-alpha

See #2

• Reorganize API to expose Spice functions, CSpice module, and Timecraft kernel loader helper separately.
• Convert to ES6 modules.
• Add an example page demonstrating using kernels and time conversion functions.
• Enable kernels to be loaded dynamically instead of requiring them to be referenced up front using pre and post install.
• Reorganize folders
• Add msl kernels into the repo

CSpice function wrappers are autogenerated in this project and can serve as a starting point for wrapping new functions. In some cases the functions must be modified a bit to work correctly, though. That script can be updated to include autogenerating typescript definitions / jsdoc comments.

• Change package.json license field from "Apache 2.0" to "Apache-2.0"

Removed

• Functions needed for managing spice "cells" (not sure what they do) but that otherwise seem to be unused. If needed this can be added back once a use case is presented.
• "alias" functions that map other spellings of function names to spice function. Ie "furnsh -> furnish" or "convrt -> convert".
• Sets of "derived" functions to help simplify some time conversions. Perhaps these can be added back in a separate helpers class at a later point.
• Wrapper of the error action set functions which aren't needed.
• Some wrappers for the chronos command line utility for performing time conversions which otherwise seem doable with other functions.
