Mathematical formulas are often used in scientific documents.
The formulas need to be parsed and rendered in a special way to be presented adequately, using special layout methods and fonts that are not always available with all browsers.
This class can render mathematical formulas using server side generated images. This way it can display the formulas so they appear correctly in all browsers.
