The CodeHighlighter filter depends on the "pygments" module which you can
download and install from: http://pygments.org
What the CodeHighlighter assumes the string that it's receiving is source
code and uses pygments.lexers.guess_lexer() to try to guess which parser
to use when highlighting it.
CodeHighlighter will return the HTML and CSS to render the code block, syntax
highlighted, in a browser
NOTE: I had an issue installing pygments on Linux/amd64/Python 2.6 dealing with
importing of pygments.lexers, I was able to correct the failure by adding:
raise ImportError
to line 39 of pygments/plugin.py (since importing pkg_resources was causing issues)

This filter goes through the value line by line, removing leading and
trailing whitespace on each line. It does not strip newlines, so every
input line corresponds to one output line, with its trailing newline intact.
We do not use val.split('
') because that would squeeze out consecutive
blank lines. Instead, we search for each newline individually. This
makes us unable to use the fast C .split method, but it makes the filter
much more widely useful.
This filter is intended to be usable both with the #filter directive and
with the proposed #sed directive (which has not been ratified yet.)
