Allow the entering of other costs to get more complete view of total cost of process

We are able to get cycle cost now, by adding time to activities and assigning the role to the activity. But that doesn't cover all the costs that may be associated with a process. Would be nice to be able to enter other costs as well, such as software cost, storage at Iron Mountain, etc. This would allow us to get a more complete view into the total cost for that process.
