Make 'jsdoc' a peer dependancy.

[wotsyula]

Really cool project.. I look forward to seeing it completed. I'd like to request that jsdoc be added as a peer dependency and not a dependency so this tool will work with whatever version of jsdoc I am currently using instead of duplicating jsdoc. Unless there is a good reason to do so you should give everyone the option of using their own version of jsdoc.

I'd like to add to this to say that the project would be easier to handle on CI servers if I didn't have to globally install jsdoc
