[Openspace] Nominal variable

[Julia Koschinsky]

There's no direct way to do this since GeoDa is designed for continuously distributed data. However, with small numbers of nominal categories, you can trick the quantile map into representing nominal categories.

E.g., with St. Louis dataset:
1. Sort State_Name and select Illinois
2. Right-click table: save selevted obs - dummy
3. Right-click map: quantile-map dummy - 3 categories

It'll display the two states.
