WFMF12 — Section 2 needs an overview

Summary: Section 2 needs an overview. There should be discussion of how a
workflow process works, i.e., how the different elements come into play,
including (1) how a process gets initiated, (2) the invokation of a
sub-process and (3) the use of a sub-process to obtain a resource
assignment. We know this stuff, but others do not and we won"t always
be around to explain it. The diagram in Section 2.12 helps, but it is
buried in the back and needs a lot more explanation.
