Tasks

•   program property
• – initWithVertexShaderByteArray:fragmentShaderByteArray:

  Initializes the CCGLProgram with a vertex and fragment with bytes array

• – initWithVertexShaderFilename:fragmentShaderFilename:

  Initializes the CCGLProgram with a vertex and fragment with contents of filenames

• – addAttribute:index:

  It will add a new attribute to the shader

• – link

  links the glProgram

• – use

  it will call glUseProgram()

• – updateUniforms

  It will create 4 uniforms:

  - kCCUniformPMatrix
  - kCCUniformMVMatrix
  - kCCUniformMVPMatrix
  - kCCUniformSampler
