Add early draft of CSS selector reference docs.
CSS selector transforms doc now lists available selectors.
Added almost all CSS modification rules to docs.
Ignore generated docs.
Detailed ^^ and ^* operators in docs.
Add some more general details on CSS transforms.

This includes the fact that they’re just
(NodeSeq)=>NodeSeq.
Add information about transformation functions.
Fixed a couple of markup errors in docs.
Add dexy config to output stuff into target/docs.
Add and annotate sample CSS transform input/output.
Do basic example extraction from dexy using Ruby script.

Not doing anything with the extracted examples yet, but this gives us the
starting point from which we can look at how we can read in a file, find the
examples in it, and run them. Ultimately, we're going to want to do this all
in Scala with CSS selector transforms, because hey, why not.
Add some info on combinint CSS selector transform.
Add documentation helpers project.
Add extract-css-selector-examples bash runner.

We use it to fire off the documentation helpers' ExtractCssSelectorExamples
application. Currently it's just a stub, more to come on that front.
Add selector class to selector examples.

We’re going to be using this to extract the selectors.
Extract CSS selector examples.

We’re not doing anything with them yet, but we’re extracting
the input, output, and selector function.
Fix dexy invocation of selector example extractor.

We now want to be passed the directory that the built HTML
is in, and we also have to compute it.

Additionally, we make use of the DEXY_ROOT environment
variable that dexy sets for us to know the project’s root
directory for proper invocation of sbt (we were computing this
in a somewhat brittle way before).
Drop extract-contents Ruby prototype.

It was just getting started, but we’ll be doing things with Scala
and Lift thanks ;)
Generate tests from documentation examples.

We generate them as files in the documentation-helpers
sbt sub-project, which can then be used to run them. Currently
the examples don’t compile yet, more to come on that front.
Dexy runs generated tests for selector examples.

We rename the example-verification target to
example-extraction, and make example-verification a target
that runs its own shell script.
