Functions
JKQTMATHTEXT_LIB_EXPORT QString	JKQTMathTextNodeTree2String (JKQTMathTextNode *root)
	converts a node-tree with the given root into a string, representing the node-tree
JKQTMATHTEXT_LIB_EXPORT JKQTMathTextNode *	simplifyAndTrimJKQTMathTextNode (JKQTMathTextNode *node)
	calls simplifyJKQTMathTextNode(). In addition it tries to clear whitespace at the start and end of the tree

This method uses JKQTMathText::getTypeName()

Here is an example output for

$x_{1/2}=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

The output looks like this:
