JavaMOP that only performs source level transformation

From this version, JavaMOP only performs the source file level transformation: given the .mop specification which describes both instrumentation and monitoring details, it will output a single .aj file (for instrumentation) and a set of .rvm files (to be used by RV-Monitor for generating monitoring library).

In the older versions of JavaMOP, the RV-Monitor will be invoked internally to generate monitoring library and then the contents of library (a set of java files) together with the aspects (pointcuts etc.) will be written to a single .aj file. From now on, JavaMOP will only be responsible for generating .rvm specifications and .aj instrumentation file; and it will be the user' responsibility to invoke RV-Monitor to generate the monitoring library.
