use distinct classes for interleaved and separate numeric mxarray objects This change is the first step to improving performance of the conversion from numeric mxArray objects to octave_value objects when the mxArray objects use interleaved complex storage or when the arrays are real valued. * mex.cc (class mxArray_base_full): Rename from mxArray_number. (class mxArray_interleaved_full, class mxArray_separate_full): New classes, derived from mxArray_base_full. These classes currently do nothing different from mxArray_base_full except that the interleaved argument is omitted from the constructors. (class mxArray_base_sparse): Rename from mxArray_sparse. (class mxArray_interleaved_sparse, class mxArray_separate_sparse): New classes, derived from mxArray_base_sparse. These classes currently do nothing different from mxArray_base_sparse except that the interleaved argument is omitted from the constructors. (mxArray::create_rep): Conditionally create distinct interleaved or separate objects here.
