mechanism to add additional code-block markers (e.g. \code{}, \begin{example}) #143
Description
It's common for journals to use \code{} or
\begin{example}
2+2;
/end(example}
As code block markers. It would good to either add some of these to the grammar for marking the contained blocks as verbatim as far as the parser is concerned (or, ideally, handing them off to a user-defined language. So if I set my default language to "R", everything in a code block (perhaps users can use tm.prefs to store these?) would be handed off to the R grammar to highlight.
