switching from coverals to codecov

[lbergelson]

codecov seems to be more accurate since it incorporates a notion of "partially covered lines"
it also makes reviewing pr's easier since coverage can be shown inline during reviews with a browser plugin

[lbergelson]

don't merge this, it isn't capturing the sra test coverage yet

[codecov-io]

Current coverage is 63.981% (diff: 100%)

No coverage report found for master at 6e4e875.

Powered by Codecov. Last update 6e4e875...b7d8ba3

@yfarjoun Have you seen the browser plugin that lets you see which lines of a pull request are covered and which aren't?

@yfarjoun I'm not certain but I suspect that if the SRA tests started working the coverage would be included now. Could you review this?
