xterm 256 Color Palette

Description

•	The xterm dictionary palette is the 256 colors recognized by xterms in Unix. To avoid off by one mistakes in Maple these colors area numbered starting at 1 and color 0 in Unix is color 256.

•	The spacing of the colors does not match up exactly with the X11 colors so instead of using those names, the names in this palette are generic descriptive names.
