A lua binding for libgit 2

libgit2 and Lua is necessary to compile the source. Currently, the source is built against:

• libgit2 0.21.0

  • including the following fix: libgit2/libgit2#2439

• Lua 5.2.

The tests use busted ( see luarocks ). for the preparation of the test cases, rm, mkdir and unzip are used via os.execute

• automated tests for the library with busted ;-)

• documentation

• functions
