added dbcolumn and tableSection

added CSS for new elements on page: dbcolumn (database column) is for

pre-existing velocities selector
added dbcolumn, objectnames and determineTable

added jQuery click functions for a couple new elements and added the
determineTable function to determine which DB table goes with each
column.

generalized
generalized and optimized

to a factor of 430.
