Details: - Implemented castm and castv operations, which behave like copym and copyv except where the obj_t operands can be of different datatypes. These new operations, however, unlike copym/copyv, do not build upon existing level-1v kernels. - Reorganized projm, projv into a 'proj' subdirectory of frame/base (to match the newly added frame/base/cast directory). - Added new macros to bli_gentfunc_macro_defs.h, _gentprot_macro_defs.h that insert GENTFUNC2/GENTPROT2 macros for all non-homogeneous datatype combinations. Previously, one had to invoke two additional macros--one which mixed domains only and another that included all remaining cases--in order to get full type combination coverage. - Defined a new static function, bli_set_dims_incs_2m(), to aid in the setting of various variables in the implementations of bli_??castm(). This static function joins others like it in bli_param_macro_defs.h. - Comment update to bli_copysc.h.
