yard-markdown gem released.

This update will be slightly different - in terms of a format. I decided to record a video instead, this way I can tell more with less effort.

I have published a first working version of yard-markdown. You can find it here:

My next goals are:

• Generate accompanying csv index filefor yard-markdown
• Integrate new markdown docsets into POSH TUI client
• Add rails docsets and make sure that client works with multiple docsets in a reasonable way.
