Made vMAT_MATv5Variable a class cluster and moved it to it's own source file.
Experiment with switching to column-major ordering; looking for better compatibility with MATLAB, BLAS, LAPACK, etc.
Eliminate an unnecessary and poorly-named local variable.
Make vMAT_pdist and vMAT_pdist2 take transposed arguments compared to their MATLAB equivalents, so vDSP_distancesq can have strides of 1.
Define vMAT_MAXDIMS (4).
Use vMAT_Size for variable dimensions (instead of an NSArray of NSNumbers).
Implemented enough of vMAT_MATv5Variable internals that vMAT_load can actually load something.
Added a unit test to verify the layout of a 4-D array in a MAT file.
Implemented -[vMAT_MATv5NumericArray _load_miSINGLE_mxSINGLE_fromOperation:] method.
Fixed a lurking bug in the load method template's calls to the SwapA macro.
Replace the implementation of -[vMAT_MATv5NumericArray _load_miUINT8_mxDOUBLE_fromOperation:] using the macro-generic template.
