Fixup code so we are using all the generated data

This is the first of what might be several commits to get all the data
that I generating into the CLDR module

Changes are
- Updates and fixes to documentation
- Change week data code so we no longer return a hash of all the data
but now take a territory id and return the data specifically for that
territory
- Fixed up week data and calendar preferences to use territory
containment
- Added tests for the above changes
