2016-01-01 Badge for coverage

pyquickhelper is using coverage to measure the coverage of the unit tests. coveralls cannot ingest these reports when codecov does with a simple command line such as:

codecov --token=69193a28-dc79-4a24-98ed-aedf441a8249
        --file=D:\jenkins\pymy\_pyquickhelper\_doc\sphinxdoc\source\coverage\coverage_report.xml
        --commit=f30c095f5da096e5db2ba6e5e0f7e07e833a8c81

It is provided by module codecov (or github/codecov). The coverage report is also available at pyquickhelper coverage. but these kinds of website keep track of the changes. Others available websites which provide badges are mentioned on the main page pyquickhelper.
