* no longer use mexPrintf()/mexErrMsgTxt() outside mexFunction(): use exceptions to report errors, in order to be able to integrate the code in a standalone executable
* fixed a few memory leaks (other still remain)
* fixed a buffer overflow issue in the filename of the dynamic MEX (using C++ string object)
* various cosmetic cleanups
