More robust heuristics for .m files and 3 new Matlab tests. Support for Obj-C detection fully intact; all tests pass. Detection of Obj-C keywords @implementation, @property, @interface, and @synthesize removed to avoid possible conflicts with user-created Matlab function handles. Only @end is needed, which is not valid in Matlab. Matlab class files supported. Comments preceded by whitespace detected for Obj-C and Matlab.
