This adds some basic tests for task checksums to ensure that the
checksums:
* change when variables change
* change when active _remove operators are present
* don't change when the _remove operators are not active
* change when an active contains() expression is present
* dont' change a contains() expression isn't active
There is a lot of other functionality which should be added to this
test but its a start.
