Detailed Description
Parsed Math expression.
A MathExpression can be queried about its variables with getNrVariables(), and each variable's name can be queried with getVariableStr( int ).
When a calculations should be done, all variables must be set with setVariable( int, float ). Then, the calculation can be done with getValue().
