Renamed CNAME to CNAME.Disabled since there is no way, currently, to disable the CNAME by modifying the CNAME file to comment out the path, or to remove the contents of the CNAME file so the gh-pages are published to the corresponding github.io location.  This filename change will need to be reverted before the pages build again as intended.  For example, for this forked version of the repository it would be: http://danielpronych.github.io/openxc-python/doxygen/.
