Adding documentation.

[SharonIV0x86]

Currently the Vector container defined in include/Vector.h is mission detailed documentation, i will be working on adding documentation myself maybe directly with readme files or using gituhb wiki, but currently we only have the usage example of vector.

Another idea is to add comment block over each function in the Vector.h but that will significantly increase the LoCs so this is kept as a future idea when the functions/methods definitions and declarations are moved into separate files .c and .h files, or a static library used is added.
