 * `max` - computes maximum of all children values

 * `clamp` - unary node that clamps its operand value into [0,1] range

+For practical reasons, we have decided to implement one optimization. Value literals may be also encoded as simple float numbers (instead of objects) in the child list. The `value`-typed objects and float literals are treated as equal; however, root node must be always an object (even when it is a literal).
