All JSDocs tags that are supported by documentjs aren't documented

for example **constructor** (is in jsdoc, so it's okay...), **codestart** tags are parsed by documentjs but isn't documented. At the same time **extends** (although there is _inherit_ tag for it), **version** tags, for example, aren't understood by documentjs, but it isn't called out anywhere. I'm calling this out because the github readme of documentjs repo says

> Specify your code's behavior precisely with JSDoc and Google Closure Compiler annotations.

Start by reviewing the documentation and the README claim about JSDoc and Google Closure Compiler annotations, then compare it with the tags documentjs parses. Check the examples mentioned—constructor, codestart, extends, and version—and document which tags are supported or unsupported; done means the documented behavior matches the parser.
