Check for more matching returns and param type checks

[brettz9]

require-returns and require-returns-check are quite helpful, and we could exploit this kind of parsing of function bodies further by checking that that the type expressed matches the type returned (rather than merely testing against presence). (Make sure to check that @returns {undefined} is tested as well, as it too benefits from checking in case the type returned--even if confirmed by require-returns-check as being present--is not undefined.)

This is a very limited form of type checking, and it is very hard to implement. Fortunately typescript --checkJs already solved this. it will read types from Jsdoc @params and @returns and do type-checking just like typescript. I use it at work, it is awesome. https://github.com/microsoft/TypeScript/wiki/Type-Checking-JavaScript-Files

So I am against this feature addition.

Good to know, thanks. Will save ourselves some work then. :)
