refactored

## Notes

I required the new version of the gem, I don't thing @cmcarthur has released it to RubyGems yet.  For now you can pull in the source for the gem, cd into the directory and run the following command to build it:

```
nothing to commit (working directory clean)
owen@owen-P55H-CM:~/dev/RJMetrics-ruby$ rake -T
rake build  # Build Gem with development dependencies
rake doc    # Generate docs
rake test   # Run RSpec unit tests
owen@owen-P55H-CM:~/dev/RJMetrics-ruby$ rake build

Select gem to uninstall:
 1. rjmetrics-client-0.1.0
 2. rjmetrics-client-0.2.0
 3. All versions

> 1 <= can choose 2 here instead if you want to keep 0.1.0
