/**
	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.
	<p>

	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...
