Add IProcessRules

Process Rules
Returns a list of all active workflow rules. If a rule has actions, the actions will be listed under the rule. Can also be used to trigger all workflow rules that are associated with a specified record. The actions for a rule are only fired if the rule’s criteria is met. When using a POST request, if anything fails, the whole transaction is rolled back.
