/**
 * A <tt>CacheManager</tt> is the primary mechanism for retrieving a {@link Cache} instance, and is often used as a
 * starting point to using the {@link Cache}.
 * <p/>
 * <tt>CacheManager</tt>s are heavyweight objects, and we foresee no more than one <tt>CacheManager</tt> being used per
 * JVM (unless specific configuration requirements require more than one; but either way, this would be a minimal and
 * finite number of instances).
 * <p/>
 * Constructing a <tt>CacheManager</tt> is done via one of its constructors, which optionally take in a
 * {@link org.infinispan.configuration.cache.Configuration} or a path or URL to a configuration XML file.
 * <p/>
 * Lifecycle - <tt>CacheManager</tt>s have a lifecycle (it implements {@link Lifecycle}) and the default constructors
 * also call {@link #start()}. Overloaded versions of the constructors are available, that do not start the
 * <tt>CacheManager</tt>, although it must be kept in mind that <tt>CacheManager</tt>s need to be started before they
 * can be used to create <tt>Cache</tt> instances.
 * <p/>
 * Once constructed, <tt>CacheManager</tt>s should be made available to any component that requires a <tt>Cache</tt>,
 * via JNDI or via some other mechanism such as an IoC container.
 * <p/>
 * You obtain <tt>Cache</tt> instances from the <tt>CacheManager</tt> by using one of the overloaded
 * <tt>getCache()</tt>, methods. Note that with <tt>getCache()</tt>, there is no guarantee that the instance you get is
 * brand-new and empty, since caches are named and shared. Because of this, the <tt>CacheManager</tt> also acts as a
 * repository of <tt>Cache</tt>s, and is an effective mechanism of looking up or creating <tt>Cache</tt>s on demand.
 * <p/>
 * When the system shuts down, it should call {@link #stop()} on the <tt>CacheManager</tt>. This will ensure all caches
 * within its scope are properly stopped as well.
 * <p/>
 * Sample usage:
 * <pre><code>
 *    CacheManager manager = CacheManager.getInstance("my-config-file.xml");
 *    Cache&lt;String, Person&gt; entityCache = manager.getCache("myEntityCache");
 *    entityCache.put("aPerson", new Person());
 *
 *    ConfigurationBuilder confBuilder = new ConfigurationBuilder();
 *    confBuilder.clustering().cacheMode(CacheMode.REPL_SYNC);
 *    manager.createCache("myReplicatedCache", confBuilder.build());
 *    Cache&lt;String, String&gt; replicatedCache = manager.getCache("myReplicatedCache");
 * </code></pre>
