Add tests to write.
Starting to implement cfs 'reassessment'. Handle removing files or directories.
Add another placeholder test
Added tests for adding file/directory to cfs storage for a file group and then reassessing.
Reword a couple of steps to make them clearer.
Add button on bit level file group to run cfs assessment.
Prevent manual start of simple assessment on file group if any cfs directory for it is being assessed.
Only do the assessment if appropriate, and add message when not.
