category feature #92
Description
Hi Kenny,
This is a great little tool you have here! I wanted to add a category dimension to the basic WordCloud, and I found this easy to do with just a few slight modifications. Essentially I just added an optional int category to WordFrequency which is an integer index within the range of colors in ColorPallate and defaults to -1. If this value is greater than or equal to 0 than use this index to select the color, otherwise select one at random (the default).
Please let me know if you would like me to submit a PR with this feature, and if so, if there is a particular way you wish to have it implemented (EG perhaps with a matching frequency analyzer implementation).
Cheers, and thank you for sharing your work!
