Uses files-diff to retrieve a list of changed files and then filters it down to runnable specs then runs them

rspec-changed.sh

#!/bin/bash

changedSpecFiles=$(files-diff | grep '^spec' | grep -v 'spec/support' | grep -v 'spec/factories')
joinedSpecFileNames=$($changedSpecFiles | tr "\n" " ")

spring rspec "$@" $($joinedSpecFileNames)

I should probably update this so that it just hunts for anything ending in _spec.rb rather than trying to exclude specific folders.
