[CM] Test coverage

[Woody Douglass]

All,

I've been thinking about writing a coverage-report-generator for s7.
I'm thinking about the kind of reports you see on codecov.io and the
like. Is there a way to hook on execution of a given s7 form? if not, I
would consider attempting to add something like that via a patch, but
i'm just making sure i'm not reinventing any wheels here

thanks,
Woody Douglass
