Subcategory for events

[SamuelmdLow]

I think the legend should split events by subcategories instead of immediately by hosts. The seminar page needs this especially since there are so many hosts.

Each subcategory would have a colour range. The legend lists the subcategories and under each subcategory is listed the hosts with events in those subcategories. A host subcategory pair is attached to a colour within the subcategory colour range. This way we can visually organize by host and subcategory at the same time.

I don't think we should use a new field for this. We can just append the subcategory to the cateogry field. For example "entertainment - music"

The difficult part of this is deciding what subcategories to include for each category and how to make them distinct. For example consider the "entertainment" category with subcategories "music" and 'theater". Which one would musical theater be? Would a stand up comedy show fit in theater or do we need a rarely used "comedy" subcategory? We need to consider what is most useful to the user.
