v0.7.0

Fix angle multiplication (#189).

Adds strict to MathGlyph (default is False). Strict means that line segments are not converted to curve segments with (0,0) control points and offcurves stacked on on-curves are not filtered out when extracting. (#235).

Last version to support Python 2 (you may need to change the requirement for fonttools if Python 2 support is giving you issues).
