- Added a "texturingEnabled" flag in fragment shader. Such uniform variable is set from OpenGL class.
- Removed Mesh constructor which took a file path as an argument. Now the user must create an emtpy Mesh and then call Mesh::loadFile().
- Now the VBO data in Mesh and TexturizedMesh classes is set using glBufferSubData() instead of glMapBuffer().
- Added debug messages.
- Added initialization code in both Mesh and TexturizedMesh classes.
