Remove methods/scenarios? List current methods/scenarios?

[mengyin]

It might be desired to have a function to list all methods/scenarios of the current dsc object?

There are no functions to directly remove some methods/scenarios from a dsc object neither....

I have added functions listMethods and listScenarios do the listing.
I'm going to resist implementing methods for removing methods/scenarios for now, as
I think it encourages the kind of interactive use that leads to difficulty reproducing results. I prefer people to keep the script that creates the dsc and recreate from scratch each time it is run....
