Clean up MEX example code.
* myfeval.c: Use mxIsChar rather than deprecated mxIsString.
* mypow2.c: Validate that input is a double matrix.
* myprop.c: Use space after '!' operator to conform to Octave conventions.
* myset.c: Use mexPutVariable instead of missing mxSetName and deprecated
mexPutArray. Find existing variable EITHER in global workspace OR in
caller workspace. Don't check both.
* mystruct.c: Clarify input validation message.
