Added time class
Fixed namespace of time util
Added project to test performance between CPU and GPU
First approx of sobel performance test. sobel process is 20 times faster in GPU than in CPU. But GPU needs the image to be uploaded. ¿Why so slow? ¿May be SOIL trouble? Design performance improvements with double threading etc...
Added constructor to Texture class to build texture from an array of data.
Testing texture loading with raw array
Fixed texture loading from file (Increased speed). Finalized sobel performance test (CPU VS GPU)
Cleaning test's code
Re-factor of sobel performance test.
Forgotten file SobelGPU.cpp
Fixed unused variable in SobelGPU.cpp
Fixed time counter in SobelPerformance Test
Modified makefile in sobelPerformance Test
Changed texture creation parameter
Fixed time counter in SobelGPU
Fixed image access indexes in SobelCPU. Saved result of sobel process with CPU
Erased extra -g flag in makefile
Improving Sobel shader. Coded but not tested
Merge branch 'SobelPerformance' of http://github.com/Bardo91/GLHL into SobelPerformance
Added security to uniform selection. Recoded sobel improved fragment
