Today I Learned Editing and Running Multiple Ruby Files in Vim

Here's a quick way to open several

1. Open the executable and all the supporting lib files in tabs in Vim, and
2. Set a hotkey to run the gem from any of the tabs.

For example, take a gem in:

/Users/you/working/sample_gem

with a basic structure of:

|-- bin | -- sample_gem -- lib |-- sample_gem | |-- bar.rb | |-- baz.rb | |-- biz.rb | |-- foo.rb | -- version.rb -- sample_gem.rb
