Initial creation

change name to rack-respond
adjust directory structure
edit READ.me
remove versions
create file for the gems version
make rack-respond file so user maintains naming conventions
edit gemspec file

To do's:

I need to remove all versions of the published gem, rack_health_check_gem
I need to edit this gem's name
I need to learn how to test middle ware gems locally 
@chadwpry because there was a new commit on this branch I had to update my fetched branch, remotes/github/initial-creation. Instead, I removed it locally, fetched it again and merged into my local branch, initial-creation, which contains more tests. Did I walk through the right practice in order to update my branch with the latest commit from @chadwpry?
