Updated the math library to use inbuilt functions

[TheKing0x9]

This pull updates the Dome Math library to use the inbuilt functions for min, max and clamp., The changed functions are

• Math.min (a, b)
• Math.max(a, b)
• Math.mid (a, b, c)

Also, a new function Math.clamp (number, min, max ) has been added which is a wrapper around the inbuilt Num.clamp function

This is great. You just need to add Math.clamp to the documentation and this looks good to merge :)

Feel free to add yourself to the AUTHORS file also!

The documentation for Math.clamp has been added.
