"""Pull some information from equations

User sreeroopnaidu requested equation export. Equations are made up internally of
<w:m> elements. Previous versions of Docx2Python ignored these elements. These are
now recognized.

Equations in Word's Professional format will return garbage.
Equations in Word's Inline format will return a nice string.
