Clarity about clearing coverband trackers and/or cache.

[michaeldeitcher]

Coverband has been a very useful tool for me. I am currently removing dead code on a project in which I recently disabled the use of a specific feature. Once deployed, I'd like to verify that specific code is no longer being executed.

I'd like to verify the runtime usage of code after the time of deployment. It does not seem that the reports can be scoped by the date of deploy. It looks like the only method to do this would be to clear cache and/or trackers.

Some questions about clearing coverband data:

• What's the difference between clearing trackers and clearing coverage?
• What are the risks to running rake coverband:clear ? How dangerous is doing this?
• Is there a way set config.web_enable_clear so only individual files can be clear not all of the project? Since clearing all coverband data is seen as being a dangerous operation.
