All the default highlight groups are present, but, now, most of them are
commented.
Each time a decision is made on what color should be used, the
corresponding groups will be uncommented.
Firstly, an error has been corrected in the utility function named
hsv2rgb.
Secondly, some of the more useful highlight groups have been processed,
but everything may still change.
The Odyssey colorscheme is based on a 12-color palette, and the main
ambiance is represented by a dark shade of green whose origins come from
the light sea green color.
Two new helper functions have added to help in the setup of the
colorscheme.
- hsv2rgb: This 1st function generate the RGB hexadecimal string
associated to a color given its HSV triplet.
- HL: This 2nd function is a wrapper for the 'highlight' command.
