executor simplification
Merge pull request #58 from estenberg/master

Small cf-execd simplification
Proper formatting of function return types.
Remove confusing description
Talking about negating the regular expression right after a good
description of its behavior made me stop and read it twice.
Short intro to functions, esp with return type `class`.
Formatting function documentation.

Reordering of blocks, and using parameter names instead of
arg1...argN. Needs review before continuing.
Merge pull request #59 from nickanderson/cleanup/reference/promise-types/classes.markdown

Remove confusing description
Contrast example with unnamed paramters.
This is just output of the example...
Batch of reformatted function documentation.
Functions that return false actually don't unset classes.

Class remains untouched.
Consistent function formatting up to 'f'.
Merge pull request #60 from estenberg/design-center

First pass at DC and DCGUI
Move things around a bit.

Technically detailed documentation a'la "here's all the stuff
you can use" in references; overview, workflows and step-by-step
instructions in manuals.

We need to introduce the Mission Portal for this to be really
making sense.
Fix meta data and make formating consistent.
Fix categories and tags.
Linebreaks.
Don't use json lexer until we know we have it.
Close code-block correctly.
Update with more guidance regarding technical documentation.
