* <p>This class can parse information from the generic binding format and
* provides Squeezebox binding information from it. It registers as a
* {@link SqueezeboxBindingProvider} service as well.</p>
*
* <p>Here are some examples for valid binding configuration strings:
*
* <ul>
* <li><code>{ squeeze="player1:title" }</code> - shows the currently playing title for the player named 'player1'</li>
* <li><code>{ squeeze="player1:artist" }</code> - shows the currently playing artist for the player named 'player1'</li>
* <li><code>{ squeeze="player1:power" }</code> - switch the player named 'player1' on or off</li>
* <li><code>{ squeeze="player1:volume" }</code> - adjusts the volume of the player named 'player1'</li>
* <li><code>{ squeeze="player1:mute" }</code> - switch the mute state of player named 'player1'</li>
* <li><code>{ squeeze="player1:play" }</code> - play the next item on playlist bound to player named 'player1'</li>
* <li><code>{ squeeze="player1:pause" }</code> - pause the current song on player named 'player1'</li>
* <li><code>{ squeeze="player1:stop" }</code> - stop the current song on player named 'player1'</li>
* <li><code>{ squeeze="player1:sync:player2" }</code> - synchronise 'player2' with 'player1'</li>
* </ul>
