====== Mathex Library ======

The mathex library exposes more functions to the built-in Lua math library. 

The following functions are exposed by this library:

//number// **Distance2D**(//number// x1, //number// y1, //number// x2, //number// y2);
  * **Parameters**
    * x1 - The first coords X axis.
    * y1 - The first coords Y axis.
    * x2 - The second coords X axis.
    * y2 - The second coords Y axis.
  * **Returns**
    * //number// - The distance between the two given coords.

//number// **Distance3D**(//number// x1, //number// y1, //number// z1, //number// x2, //number// y2, //number// z2);
  * **Parameters**
    * x1 - The first coords X axis.
    * y1 - The first coords Y axis.
    * z1 - The first coords Z axis.
    * x2 - The second coords X axis.
    * y2 - The second coords Y axis.
    * z2 - The second coords Z axis.
  * **Returns**
    * //number// - The distance between the two given coords.

//number// **DegreeToRadian**(//number// deg);
  * **Parameters**
    * deg - The degree to convert to a radian.
  * **Returns**
    * //number// - The converted radian.

//number// **RadianToDegree**(//number// rad);
  * **Parameters**
    * rad - The radian to convert to a degree.
  * **Returns**
    * //number// - The converted degree.

//number// **Clamp**(//number// num, //number// l, //number// h);
  * **Parameters**
    * num - The number to clamp.
    * l - The low value to clamp within.
    * h - The high value to clamp within.
  * **Returns**
    * //number// - The clamped value.

//number// **Round**(//number// num, //number// dp);
  * **Parameters**
    * num - The number to round.
    * dp - The number of decimal places to round to.
  * **Returns**
    * //number// - The rounded value.

//number// **ToD3DColor**(//number// a, //number// r, //number// g, //number// b);
  * **Parameters**
    * a - The alpha color.
    * r - The red color.
    * g - The green color.
    * b - The blue color.
  * **Returns**
    * //number// - The 32bit color code.
