PROMT: Replace table layout for session listing

[inghamn]

The information that is desired is way more than we can display in a table format. We need to rework how session information is displayed.

https://bloomington.in.gov/recreation/programs/10550

Each of the code numbers (e.g. 325001-A and -B) point to a different level. 325001 is Parent & Tot. That info doesn't show up in the table on the website, so it's quite the jumble of listings. The levels and descriptions of the classes are found in the "Description" field in PROMT, Program ID# 10550.

We probably need to do an individual "Enroll" button for each session listed, as each session can be for a completely different activity in RecTrac.

This repository is probably where we'll do the real HTML work for:
