/**
* Keyboard Building helper.
*
* This class parses Keyboard XML file and eventually build a Keyboard.
* The Keyboard XML file looks like:
* <pre>
* &lt;!-- xml/keyboard.xml --&gt;
* &lt;Keyboard keyboard_attributes*&gt;
* &lt;!-- Keyboard Content --&gt;
* &lt;Row row_attributes*&gt;
* &lt;!-- Row Content --&gt;
* &lt;Key key_attributes* /&gt;
* &lt;Spacer horizontalGap="32.0dp" /&gt;
* &lt;include keyboardLayout="@xml/other_keys"&gt;
* ...
* &lt;/Row&gt;
* &lt;include keyboardLayout="@xml/other_rows"&gt;
* ...
* &lt;/Keyboard&gt;
* </pre>
* The XML file which is included in other file must have &lt;merge&gt; as root element,
* such as:
* <pre>
* &lt;!-- xml/other_keys.xml --&gt;
* &lt;merge&gt;
* &lt;Key key_attributes* /&gt;
* ...
* &lt;/merge&gt;
* </pre>
* and
* <pre>
* &lt;!-- xml/other_rows.xml --&gt;
* &lt;merge&gt;
* &lt;Row row_attributes*&gt;
* &lt;Key key_attributes* /&gt;
* &lt;/Row&gt;
* ...
* &lt;/merge&gt;
* </pre>
* You can also use switch-case-default tags to select Rows and Keys.
* <pre>
* &lt;switch&gt;
* &lt;case case_attribute*&gt;
* &lt;!-- Any valid tags at switch position --&gt;
* &lt;/case&gt;
* ...
* &lt;default&gt;
* &lt;!-- Any valid tags at switch position --&gt;
* &lt;/default&gt;
* &lt;/switch&gt;
* </pre>
* You can declare Key style and specify styles within Key tags.
* <pre>
* &lt;switch&gt;
* &lt;case mode="email"&gt;
* &lt;key-style styleName="f1-key" parentStyle="modifier-key"
* keyLabel=".com"
* /&gt;
* &lt;/case&gt;
* &lt;case mode="url"&gt;
* &lt;key-style styleName="f1-key" parentStyle="modifier-key"
* keyLabel="http://"
* /&gt;
* &lt;/case&gt;
* &lt;/switch&gt;
* ...
* &lt;Key keyStyle="shift-key" ... /&gt;
* </pre>
