#SourcePawn NavMesh
This is basically a SourceMod plugin that can parse .NAV files and make data out of it that SourceMod plugins can read from. This plugin by itself doesn't do anything other than read data from the .NAV file. Other plugins have to utilize this plugin's features in order for this to have any purpose.
Special thanks goes to Anthony Iacano (pimpinjuice) for the parser code, which can be found here: https://github.com/AnthonyIacono/War3SourceV2/tree/master/Nav
