Move RangeSet from Externals to Common

Browse Source 
This is a very small libary, and as I understand it, it was more or less
developed for Dolphin.

This moves the two relevant files from Externals to Common, changes the
namespace to Common, reformats the code, and adds Dolphin copyright
notices. The change in copyright notice and license was approved by
AdmiralCurtiss.
