Merge "Refactor unit test data" into casablanca

Refactor unit test data

There were many copies of test policies and examples
strewn through the Apex unit tests. This change cleans
up the unit tests so that a single version of all example
policies is used in all tests.

Also added a new relative file root command line parameter
to Apex to allow the root of relative paths in configuration
files to be set.

Apologies for the size of this review but unfortunately
all of this must be done in one shot.
