Made button clicks functional

-Made clicking filter buttons functional instead of programmed per case.
Now the ID determines the TYPE of filter (day, time, other), and the
value determines which filter to use under that type (ie. value="0"
where 0 corresponds to the position of the Monday filter object in the
array).
-Moved filter array initialization into it's own function.
-Beginning overhaul of determineHighlightFilters function (currently
incredibly convoluted).
Finished determine highlight filters function

Finished up determine highlight filters function. Needs bug fixing with
"Other" filters.
