2D Amortized Noise Generator

This project demonstrates how the 2D amortized noise algorithm can be used to produce an infinite greyscale tiled texture. It will prompt the user via stdin/stdout for the texture size (which must be a power of 2), a seed value, the largest and smallest octaves, and tile coordinates in row-column format. The input values are checked for errors. If they pass, the tile texture will be saved in a png file (windows) or tga file (other OS). The amount of user CPU time used in generating the noise is reported to stdout. Saved files will be named i[F]s[N]o[LS]s[D]r[R]c[C].X (for example, i1s256o25s5432r54c33.png), where:

F0 for finite or 1 for infinite
Ntile side
Llargest octave
Ssmallest octave
Xpng or tga
