Public Member Functions
	GLProgram (std::string name)
	GLProgram constructor.
	~GLProgram ()
	GLProgram destructor.
GLuint	handle () const
	returns the program handle
void	addShader (GLShaderPtr)
	add a shader to the program
void	removeShader (GLShaderPtr)
	remove a shader from the program
void	link ()
	link the glsl program from a set of compiled shaders Much like C++ linking takes a set of object files and builds a complete program from them so too does glsl.
void	enable ()
	enable the glsl program enabling a glsl program means rendering will now use your glsl program instead of the fixed pipeline rendering
void	disable ()
	disable the glsl program disabling a glsl program completely disables the usage glsl programs and goes back to fixed pipeline renering
void	setUniform (std::string uniformName, int value0)
	set a uniform using 1 integer values
void	setUniform (std::string uniformName, float value0)
	set a uniform using 1 float values
void	setUniform (std::string uniformName, int value0, int value1)
	set a uniform using 2 integer values
void	setUniform (std::string uniformName, float value0, float value1)
	set a uniform using 2 float values
void	setUniform (std::string uniformName, int value0, int value1, int value2)
	set a uniform using 3 integer values
void	setUniform (std::string uniformName, float value0, float value1, float value2)
	set a uniform using 3 float values
void	setUniform (std::string uniformName, int value0, int value1, int value2, int value3)
	set a uniform using 4 integer values
void	setUniform (std::string uniformName, float value0, float value1, float value2, float value3)
	set a uniform using 4 float values
