preliminary version of documentation for module developers

This is still very VERY much a work in progress, but it's a start, and
this way Yu and I can both edit it.
Updated readme to fix some typos, etc.
Update README.rst
checking in last night's changes to documentation

Added a checklist for experienced authors and fleshed out sections of
other pages.
drug design (first draft of first module) and more tweaks to developer documentation
Merge branch 'try-kinge'
drafts of assorted modules, just for backup

documentation for authors needs to be reviewed, preferably by someone
trying to write a module.

Merge branch 'try-kinge'
finished epidemic module

At least as much of it as comes from my end - Mac crew, it's now yours

added folder of code to epidemic module

now it's really all yours, Mac crew. we talked in the meeting today
about adding images to the intro and about us retaining the Go stuff for
ourselves, but otherwise consider the token officially passed.
completed draft of drug design modules

Would love feedback on either/both (Exemplar, which is a problem
definition and sequential code; In Parallel, which is four different
implementations and discussion thereof)

added minimal information to docs directory (most content is in deve directory for now).
