Add activity diagram for expense

[liakify]

Activity diagram looks good! @liakify give us a heads up when you want it merged.

Aside: actually, for the section where the Expense commands loops through the participants supplied, that can actually be represented as a branching statement that loops back to a diamond until it runs out of participant names. I think that's the convention for loops, so you might want to consider that in place of 'For each person, search for contacts in the search scope using the search terms'.

I tried doing that but activity diagram loops are structured more like while loops and it was kinda hard to specify the looping condition in a way that still made sense for reading & doc purposes (or maybe its just my english).

But yes pls merge
