Segment Tree V1.0.0

This is the initial build that lives in PyPI and is built when running pip install c-segment-tree.

This does not work on Windows since it does not have a native C compiler. Using C/C++ build tools from Visual Studio doesn't work since it does not compile to C99 which is needed. If I could figure out how to do it, I could install those Windows tools and add the wheel file to the build.
