Workflow wrapper class

[mwdchang]

Summary

Wrap workflow data structure inside WorkflowWrapper class to make accidental data corruption less likely. There are a lot of changes but basically they are of the form:

From

blah = workflowService.doSomething(wf, param1, param2, ...)

To

blah wf.doSomething(param1, param2)

If you use the WorkflowWrapper then generally speaking you don't need to deal with isDeleted and version flags.
