Adds an option (-m, --min_coverage, or {cover_opts, {min_coverage,X}})
to the 'cover' command, where the value is an integer between 0 and 100.
If the total coverage during the analysis is below the value received,
the command will fail with output like:
===> Requiring 64% coverage to pass. Only 62% obtained
If the rate is correct, the command silently passes as it currently
does.
This feature allows to enforce code coverage standards in a project if
desired.
