/**
    Return the name of the file or source from which the current interpreter
    is reading.  Note that if you use this within a method, the result will
    not be the file from which the method was sourced, but will be the file
    that the caller of the method is reading.   Methods are sourced once but
    can be called many times... Each time the interpreter may be associated
    with a different file and it is that calling interpreter that you are
    asking for information.
    

    Note: although it may seems like this command would always return the
    getSourceFileInfo.bsh file, it does not since it is being executed after
    sourcing by the caller's interpreter.
    If one wanted to know the file from which a bsh method was sourced one
    would have to either capture that info when the file was sourced (by
    saving the state of the getSourceFileInfo() in a variable outside of
    the method or more generally we could add the info to the BshMethod class
    so that bsh methods remember from what source they were created...
