/**
* The bridge interface
*
* A bridge is a class that is responsible for collecting and transforming data
* from one hosting provider into an internal representation of feed data, that
* can later be transformed into different feed formats (see {@see FormatInterface}).
*
* For this purpose, all bridges need to perform three common operations:
*
* 1. Collect data from a remote site.
* 2. Extract the required contents.
* 3. Add the contents to the internal data structure.
*
* Bridges can optionally specify parameters to customize bridge behavior based
* on user input. For example, a user could specify how many items to return in
* the feed and where to get them.
*
* In order to present a bridge on the home page, and for the purpose of bridge
* specific behaviour, additional information must be provided by the bridge:
*
* * **Name**
* The name of the bridge that can be displayed to users.
*
* * **Description**
* A brief description for the bridge that can be displayed to users.
*
* * **URI**
* A link to the hosting provider.
*
* * **Maintainer**
* The GitHub username of the bridge maintainer
*
* * **Parameters**
* A list of parameters for customization
*
* * **Icon**
* A link to the favicon of the hosting provider
*
* * **Cache timeout**
* The default cache timeout for the bridge.
