/** is the base for AddIn services that supply functions which can be called
	by other components.

	<p>Any AddIn implementation must implement a service describing its
	specific set of functions.
	That service must contain the <type>AddIn</type> service, and the
	functions that are implemented, in one or more interfaces.
	The <type scope="com::sun::star::lang">XServiceName</type> interface
	must describe that service, and the <type>XAddIn</type> interface
	must describe the individual functions.</p>

	<p>Each AddIn function can take parameters of the following types:</p>

	<dl>
	<dt><atom>long</atom></dt>
	<dd>for integer values.</dd>

	<dt><atom>double</atom></dt>
	<dd>for floating point values.</dd>

	<dt><atom>string</atom></dt>
	<dd>for text strings.</dd>

	<dt><atom>long[][]</atom></dt>
	<dd>for (two-dimensional) arrays of integer values.</dd>

	<dt><atom>double[][]</atom></dt>
	<dd>for (two-dimensional) arrays of floating point values.</dd>

	<dt><atom>string[][]</atom></dt>
	<dd>for (two-dimensional) arrays of text strings.</dd>

	<dt><atom>any[][]</atom></dt>
	<dd>for (two-dimensional) arrays of mixed contents. Each <atom>any</atom>
	will contain a <atom>double</atom> or a <atom>string</atom>, depending on
	the data.</dd>

	<dt><atom>any</atom></dt>
	<dd>Depending on the data, a <atom>double</atom>, a <atom>string</atom>,
	or an <atom>any[][]</atom> will be passed. If no argument is specified in
	the function call, <void/> will be passed. This allows for optional
	parameters.</dd>

	<dt><type scope="com::sun::star::table">XCellRange</type></dt>
	<dd>for a <type scope="com::sun::star::table">XCellRange</type> interface
	to the source data.</dd>

	<dt><type scope="com::sun::star::beans">XPropertySet</type></dt>
	<dd>for a <type scope="com::sun::star::beans">XPropertySet</type>
	interface to the <type>SpreadsheetDocument</type> making the function
	call. Only one parameter of this type is allowed in each function. It
	can be used to query document settings like
	<member>SpreadsheetDocumentSettings::NullDate</member>.</dd>

	<dt><atom>any[]</atom></dt>
	<dd>for varying parameters. Only the last parameter of a function may
	have this type. It will be filled with the remaining arguments of the
	function call that were not used for the previous parameters. Each
	element of the sequence will be filled as in the case of <atom>any</atom>
	above.</dd>
	</dl>

	<p>Each AddIn function must have one of the following return types:</p>

	<ul>
	<li><atom>long</atom></li>
	<li><atom>double</atom></li>
	<li><atom>string</atom></li>
	<li><atom>long[][]</atom></li>
	<li><atom>double[][]</atom></li>
	<li><atom>string[][]</atom></li>
	<li><atom>any[][]</atom></li>
	<li><type>XVolatileResult</type></li>
	<li><atom>any</atom></li>
	</ul>

	<p>The sequences must contain arrays as described above for the
	parameter types.
	An <type>XVolatileResult</type> return value must contain an object
	implementing the <type>VolatileResult</type> service, that contains
	a volatile result. Subsequent calls with the same parameters must
	return the same object.
	An <atom>any</atom> return value can contain any of the other types.</p>
