changed call from finite() to isfinite(). because finite() has been deprecated for a decade(ish).
added class data to the dictionary
Fixed improper type casting in C code for meshes. This enables using 64bit VTK. Added compiled 64 bit mac mex files for build_mesh and smooth_mesh.  I'm not sure if the mex files will work with other mac's with different VTK installs.  Needs to be tested.
Added code to unify the handling of class files with the new handling of volume anatomy. This code should handle class nifti's the same way volume anatomy nifti's are handled.
Added comments and re-fixed the handling of pixel dimensions to correspond to the permutation contortions for the class data.
Added statically linked versions of build_mesh mex files.  Built under OSX 10.6.8 with vtk-5.10.1
