MathCustomFunctionsImplemented class

Set of custom implemented 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.
