Simplified API for vector based spatial analysis.

I am the author of TdhGIS, a simplified vector based GIS, free for non-commercial use. I have now taken the 2 libraries needed to perform the spatial analysis calculations, along with the necessary header files, and released them as an API. I believe this package provides a far easier path for adding spatial analysis functionality to a software project than what is otherwise available, and it is also free for non-commercial use. The package can be obtained from both github and the TdhGIS website. I would appreciate any feedback on how useful this might be, how it can be made more useful and how I can get the word out. Respectfully, Tim Hirrel
