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 
This is a great start but not a full test suite.  The codebase should be tested for multiple conditions.  Here are a few I would like to see evaluated.

- Are routes case sensitive?  How can this be shown via a test and what does that test need to do?

- Is the next middleware in the application chain called when a route is not matched?

- Is the default content-type "text/plain?"

- Can another content-type be set on initialization and be verified in the response when the middleware is called?

- Is the HTTP status response a success? (200)
