title: Looking for a WordPress plugin to use as an example/starting point
body: <p>I would like to write a WordPress plugin that provides the ability to maintain database of potentially detailed entries, and then a filterable view of those entries.  Specifically I would like to maintain a player roster, with a set of specific fields for each player.  It would include mostly simple fields, though I foresee needing to upload and reference photos as well.</p>
  
  <p>I assume the hard part of this would be the administration page, providing your basic CRUD functionality for the table, then potentially the filterable view.  I also assume that this is specific enough that there is not a plugin that fits my needs out of the box.  Attempts to find one have come up empty, with one <a href="http://wordpress.org/extend/plugins/leaguemanager/" rel="nofollow">defunct</a> effort and one that is much more <a href="http://www.wp-swimteam.org/" rel="nofollow">complex</a> than I'd like to start with.</p>
  
  <p>So, can anyone point me at a good open source example of a plugin that would get me started, specifically something that creates custom table(s) and provides a CRUD like administration page for maintaining the tables.  I'm sure I could write stand alone php scripts to do this, but I'd like to write it in the context of WP, and consider releasing it back on the community.</p>
