AbstractFunctionEvaluatorast.get(0) (or alternatively ast.head()) contains the
head (i.e. the function symbol) of this abstract syntax tree (AST). ast.arg1() to ast.get(n) the ast contains the first to n-th argument of the
function (alternatively you get the first to fifth argument with the methods arg1(), arg2(),...
arg5()).Validate class to check the number or types of arguments in the evaluate
