 Written by Keith Wood (wood.keith{at}optusnet.com.au) December 2013.
 Licensed under the MIT license (http://keith-wood.name/licence.html).
 Use {@link $.JQPlugin.createPlugin} to create new plugins using this framework.
 This base class provides common functionality such as:
 <ul>
 <li>Creates jQuery bridge - allowing you to invoke your plugin on a collection of elements.</li>
 <li>Handles initialisation including reading settings from metadata -
 an instance object is attached to the affected element(s) containing all the necessary data.</li>
 <li>Handles option retrieval and update - options can be set through default values,
 through inline metadata, or through instantiation settings. 
 Metadata is specified as an attribute on the element:
 <code>data-&lt;pluginName>="&lt;option name>: '&lt;value>', ..."</code>.
 Dates should be specified as strings in this format: <code>'new Date(y, m-1, d)'</code>.</li>
 <li>Handles method calling - inner functions starting with '_'are inaccessible,
 whereas others can be called via <code>$(selector).pluginName('functionName')</code>.</li>
 <li>Handles plugin destruction - removing all trace of the plugin.</li>
 </ul>

 One of <code>until</code> or <code>since</code> must be specified.

 @property {CountdownServerSyncCallback} [serverSync=null] A function to retrieve the current server time
 for synchronisation.
 @property {string} [format='dHMS'] The format for display - upper case to always show,
 lower case to show only if non-zero,
 'Y' years, 'O' months, 'W' weeks, 'D' days, 'H' hours, 'M' minutes, 'S' seconds.
 @property {string} [layout=''] Build your own layout for the countdown.
 Indicate substitution points with '{desc}' for the description, '{sep}' for the time separator,
 '{pv}' where p is 'y' for years, 'o' for months, 'w' for weeks, 'd' for days,
 'h' for hours, 'm' for minutes, or 's' for seconds and v is 'n' for the period value,
 'nn' for the period value with a minimum of two digits,

 If you need to exclude entire sections when the period value is zero and
 you have specified the period as optional, surround these sections with

 Your layout can just be simple text, or can contain HTML markup as well.
 @example layout: '{d<}{dn} {dl}{d>} {hnn}:{mnn}:{snn}'
 @property {boolean} [compact=false] <code>true</code> to display in a compact format,
 <code>false</code> for an expanded one.
 @property {boolean} [padZeroes=false] <code>true</code> to add leading zeroes.

 receives no parameters and <code>this</code> is the containing element.
 @example onExpiry: function() {

 @property {CountdownTickCallback} [onTick=null] Callback when the countdown is updated -
 receives <code>number[7]</code> being the breakdown by period
