* This is a clean, fast, modern and free Perlin noise class in C++.
* Being a stand-alone class with no external dependencies, it is
* highly reusable without source code modifications.
*
* Note:
* Replacing the "float" type with "double" can actually make this run faster
* on some platforms. A templatized version of Noise1234 could be useful.
