A custom Velocity directive to conditionally join a number of <A HREF="../../../../../org/apache/cayenne/access/jdbc/ChunkDirective.html" title="class in org.apache.cayenne.access.jdbc"><CODE>chunks</CODE></A>.
Usage of chain is the following:
<pre>
#chain(operator) - e.g. #chain(' AND ')
#chain(operator prefix) - e.g. #chain(' AND ' 'WHERE ')</pre>
<p><code>operator</code> (e.g. AND, OR, etc.) is used to join chunks that are included
in a chain. <code>prefix</code> is inserted if a chain contains at least one chunk.
