Update CHANGELOG.
Merge branch 'release-3.0.1-branch' into develop

Replaced annulardomain sketch with svg.
Replaced annulardomain2 sketch with svg.
#99: Omit some braid relations when compacting annbraids.
Plot annular braid in guide.
(-1)^i for integer i replaced with ?: test

operator test ? : as there are only two possible outcomes.
Add to index, notes on intro sec.
Makefile MEX suffix for i686 (from Alex's computer).
