1. Add support to the simulation of fiber-optic endoscope at the inner tissue.
2. Add some new parameters and the version of the parameter file has been updated to 2.3. The latest version still supports the older versions of the parameter file.
3. Change the way of output of the detector result under CW simulation. First, output the result of the plane detector, followed by the result of fiber detector.
4. Fix the errors of the simulation property input dialog.
5. Fix some other errors, enhance the stability of the software to run, and improve the efficiency of the algorithm.
