MathCustomFunctions class
Set of custom functions
To declare a custom function, implement MathDefinitionFunctionFreeform or MathDefinitionFunctionFreeformImplemented interface and pass it as a member of the set when constructing this class.
When using MathNodeExpression.fromString, you can omit implementing the
functions, but MathExpression.calc will require you to pass a
MathCustomFunctionsImplemented instance instead, which requires
the functions to have the calc method. If you pass
MathDefinitionFunctionFreeformImplemented in fromString, you won't need
to declare the implementation when parsing.
