Support JSDoc HereComments

[vjpr]

The following creates a <h2> tag:

###* @param {string} test ###

Try this:

/**
* ### My Heading ###
*
* @param {String} param1
*/

I think the problem is that there is confusion on whether you want to use a markdown header (e.g. ### header ###) or the JSDoc param. Docco derives from Dox, so the support should already be there.
