+   * it triggers a coverage collection on the current webserver process
+   * it generates a new html coverage report and pushes it to S3

+* __view coverage report:__ Don't need to update the data just view the current report
+* __update coverage data (collect coverage):__ This triggers coverage collection on the current webserver process
+* __update coverage report (rebuild report):__ This will rebuild the HTML report from the latest available data
+* __clear coverage report:__ This will clear the coverage data. This wipes out all collected data (__dangerous__)
+* __reload Coverband files:__ This has Coverband reload files as configured (force reload of some files that might not capture Coverage on boot)
