1)The goal of this class is a class that loads/unloads image for opengl
2)Keeps track of how  images by
    -filename
    -openGLtextureID
    -image/2D image Metrics in terms of raw pixel data
3)Loads sentinal image if the image failed to load
4) Contains implementation to keep track of how many applications of this image are being used
4) Note: Does NOT  sanity check if  a given image file has been all ready loaded
