java CLOC count active lines of code in a method

    * the getCLOCVer with the function you want to test as a string parameter 2
    * paste the resulting code into this class, and delete errors with the code
    * activeLinesOfCode++; only where it errors tho 3 if the tested function has
    * private methodes used inside, extend the CALOC class with the original class
    * containing the tested function. 4 run the pasted function via an instance of
    * this class : caloc.testFunction(params); 5 caloc.getActiveLinesOfCode to see
    * how many active line of code for the parameters you have sent
