When a workitem changes, TfsRollUp looks for fields that are prefixed with
Alm.RollUp. of type Double and with a HelpText ending in
(Enabled), and if one or more fields are found, sends the workitem to further processing.
Field requirements:
- FieldName (prefix): Alm.RollUp.
- Type..........................: Double
- HelpText (postfix).: (Enabled)
