% [img, dims,scales,bpp,endian] = READ_AVW(fname)
%
%  Read in an Analyze or nifti file into either a 3D or 4D
%  array (depending on the header information)
%  fname is the filename (must be inside single quotes)
%  Note: automatically detects - unsigned char, short, long, float
%         double and complex formats
%  Extracts the 4 dimensions (dims), 
%  4 scales (scales) and bits per pixel (bpp) for voxels 
%  contained in the Analyze or nifti header file (fname)
%  Also returns endian = 'l' for little-endian or 'b' for big-endian
