all data button, css changes
change underlying data struct to allow for binding

specifically @filters changed from being a hash organized by filter type
to just an array, also adds ids to each filter, which are used across
the app
more changes to data struct

@filters is now a hash where the key is the filter id (as opposed to an
array of filters that all have a attribute id)

This will allow for faster retrieval of filters
fix weird behavior with removing all data
fix remove curr_filters bug
ability to size circles per numeric columns
