vscript_funcs_shared.cpp

//========= Mapbase - https://github.com/mapbase-source/source-sdk-2013 ============//
//
// Purpose: This file contains general shared VScript bindings which Mapbase adds onto
//			what was ported from Alien Swarm instead of cluttering the existing files.
//
//			This includes various functions, classes, etc. which were either created from
//			scratch or were based on/inspired by things documented in APIs from L4D2 or even
//			Source 2 games like Dota 2 or Half-Life: Alyx.
//
//			Other VScript bindings can be found in files like vscript_singletons.cpp and
//			things not exclusive to the game DLLs are embedded/recreated in the library itself
//			via vscript_bindings_base.cpp.
//
