Detailed Description

Extended math support.

Extends Math from Math package from base DragonScript.

Overwrites trigonometric methods to operate on degrees instead of radians. To use radians version use Math directly.

Furthermore adds some additional methods useful for game development.

This is a native class. This class is for static use only and can not instantiated but subclassed.
