Re-arranging repo files. Designing new GLHL base interface to use windowless, windowed or multiple window contexts.
Erased undefined function in DriverGPU
Changed guards according to new folder structure. Created Context.h file.
Created test to design context class
Made safe multi-context  creation (Multi-window)
Coding Context class and context creation
First approximation of windowless context creation
render without window seems to work. but thing that a windows is also created but not shown. Is any difference?
Created context class for linux but not tested. Added methods to make current contexts and windows. Tested context test with VS13 and seems to be right, but gdebugger found some error
