 * \brief Class that defines how to read MINC2 file format. Note,like
 * ITK, MINC2 is N dimensional and dimensions can be submitted in any 
 * arbitrary order. Here we make sure the dimensions are ordered as
 * xspace, yspace, zspace, time and vector_dimension and so on or
 * xfrequencey, yfrequency, zfrequency, tfrequency and
 * vector_dimension and so on
 * NOTE** This class only reads the regularly sampled dimensions as I
 * am not sure how to deal with "iregularly sampled" dimensions yet!
