Update README with development section #2
Description
"I am happy to provide fixes for something as useful as trackable. You saved me a ton of work not having to create it from scratch and implementation was very simple. I just always have odd use cases in my applications. Getting the tests running were pretty easy once i specified a RAILS_ROOT before running. The only issue I had at first was realizing that it was testing my gem installation and not the source files, but that was easily worked around. Thanks again for trackable!"
