Coverage statistics link on https://libcellml.readthedocs.io is broken

[PrasadBabarendaGamage]

The coverage statistics link on https://libcellml.readthedocs.io/en/latest/coverage_statistics.html is broken. It currently points to: https://libcellml.readthedocs.io/en/latest/coverage/index.html which gives a "sorry this page does not exist yet" message.

The text in the 'note' on https://libcellml.readthedocs.io/en/latest/coverage_statistics.html also needs to be updated from:
The coverage test sometimes (this behaviour has been observed on OS X using clang) reports single lines containing only a closing curly brace as not covered.
to:
The coverage test sometimes eports single lines containing only a closing curly brace as not covered (this behaviour has been observed on OS X using clang).

Thanks @PrasadBabarendaGamage. That link currently only works if you build the docs yourself and have coverage stats available, such as is available on the buildbot generated docs (https://autotest.bioeng.auckland.ac.nz/libcellml-buildbot/c842463cd24465354631fb1ef867f009e1d92fbd/dox/coverage_statistics.html). We hope to one day have the CI system integrate this information into the readthedocs generated docs, and hence leave the "broken" link in the docs...

As for the correction, I'm not sure I agree :) Will have to see what @hsorby thinks of it...

This issue is listed under #41, I am ok with the change but would prefer to use the word 'reports' instead of 'eports'.

Working on getting readthedocs to be able to include the coverage reports. If I can get readthedocs to add SWIG to the latest Docker image for building then I think we can make this happen.
