CVS commit by staikos: 

This flattens equations to text, but there are two problems:
1) whitespace is lost (minor)
2) parentheses are lost (major)

Solutions seem to be:
i) make a tree walker instead and have it know about order of operations,
inserting parentheses where needed (painful)
ii) store parentheses flag in each node (somewhat heavy)
