My edits to Tim's original draft proposal.

Lots of them (most discussed with Tim on chat and in person):

* wordsmithing
* reorganizing arguments
* changing recursive from int to bool
* reordering examples
* fixing $CHPL_HOME based startdir examples
* adding more topics
* etc.

My edits to Tim's original filerator draft proposal

This is what I just mailed out to chapel-users.  There are lots of changes here (most of them discussed with Tim on chat and in person).  They tend to fall into the categories of:

* wordsmithing
* reorganizing arguments
* changing recursive from int to bool
* reordering examples
* fixing $CHPL_HOME based startdir examples
* adding more topics
* etc.
