Adding MustGet method to adt.Array in order to simplify code

[laudiacay]

677

Add a mustget function so that we don’t have to do things like say if err != nil {error out} if !found {error out}

This is a draft because i want to work the new pattern into the code in at least a few places before we merge it :)
