 <div class="block">A concurrent authority factory that caches all objects created by another factory.
  All <code>createFoo(String)</code> methods first check if a previously created object exists for the given code.
  If such object exists, it is returned. Otherwise, the object creation is delegated to another factory given
  by <a href="#newDataAccess()"><code>newDataAccess()</code></a> and the result is cached in this factory.

  <p><code>ConcurrentAuthorityFactory</code> delays the call to <code>newDataAccess()</code> until first needed,
  and <a href="https://docs.oracle.com/javase/8/docs/api/java/lang/AutoCloseable.html?is-external=true#close()" title="class or interface in java.lang" class="externalLink">closes</a> the factory used as a <cite>Data Access Object</cite>
  (DAO) after some timeout. This approach allows to establish a connection to a database (for example)
  and keep it only for a relatively short amount of time.</p>

  <div class="section">Caching strategy</div>
  Objects are cached by strong references, up to the amount of objects specified at construction time.
  If a greater amount of objects are cached, then the oldest ones will be retained through a
  <a href="https://docs.oracle.com/javase/8/docs/api/java/lang/ref/WeakReference.html?is-external=true" title="class or interface in java.lang.ref" class="externalLink">weak reference</a> instead of a strong one.
  This means that this caching factory will continue to return those objects as long as they are in use somewhere
  else in the Java virtual machine, but will be discarded (and recreated on the fly if needed) otherwise.

  <div class="section">Multi-threading</div>
  The cache managed by this class is concurrent. However the Data Access Objects (DAO) are assumed non-concurrent.
  If two or more threads are accessing this factory in same time, then two or more Data Access Object instances
  may be created. The maximal amount of instances to create is specified at <code>ConcurrentAuthorityFactory</code>
  construction time. If more Data Access Object instances are needed, some of the threads will block until an
  instance become available.

  <div class="section">Note for subclasses</div>
  This abstract class does not implement any of the <a href="http://www.geoapi.org/3.0/javadoc/org/opengis/referencing/datum/DatumAuthorityFactory.html?is-external=true" title="class or interface in org.opengis.referencing.datum" class="externalLink"><code>DatumAuthorityFactory</code></a>, <a href="http://www.geoapi.org/3.0/javadoc/org/opengis/referencing/cs/CSAuthorityFactory.html?is-external=true" title="class or interface in org.opengis.referencing.cs" class="externalLink"><code>CSAuthorityFactory</code></a>,
