noteweb: Rendering bird field notes for the Web

Columns in the index table are color-coded according to the four reporting seasons for Audubon Field Notes. We provide rules for both heading (th) and normal (td) table cells. The class names are the season names. All cells have borders on the left and right, so that the entire table is ruled.
