7  Return the name of the file or source from which the current interpreter
8  is reading.  Note that if you use this within a method, the result will
9  not be the file from which the method was sourced, but will be the file
10  that the caller of the method is reading.   Methods are sourced once but
11  can be called many times... Each time the interpreter may be associated
12  with a different file and it is that calling interpreter that you are
13  asking for information.
14  <p>

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