Rake task `add_threshold` API is confusing about cane HOT 2 CLOSED

This is probably OT, but I think that metrics tools should have a way so that you can set specific thresholds that must be matched exactly or it fails the build. By that I mean, if I expect to have 95.6% coverage, and I configure the system to match that, I want things to fail if it increases to 95.7% .. that is, I want to have to be forced to "raise the bar" a tiny bit each time the actual metric improves.

I do this with other metrics, and it has really good results. Each time the code quality improves, the system notifies me and I nudge the expected value up a bit. There's a strong incentive not to lower it at all; so over time metrics improve more quickly compared to when you can only do >= comparisons with thresholds.

It should support :== and all the other operators, I intended to do so but forgot.
