Add jasmine tests for testing policy manager performance.

In the 'test/jasmine.scale.tests' and 'test/jasmine.timing.test' directory
there are now some tests that will print out how long certain policy
enforcement functions are taking to perform.  These can be run with
jasmine-node from within their respective directories.
