/**
* 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:
* <code>
* CacheManager manager = CacheManager.getInstance("my-config-file.xml");
* Cache<String, Person> entityCache = manager.getCache("myEntityCache");
* entityCache.put("aPerson", new Person());
*
* ConfigurationBuilder confBuilder = new ConfigurationBuilder();
* confBuilder.clustering().cacheMode(CacheMode.REPL_SYNC);
* manager.defineConfiguration("myReplicatedCache", confBuilder.build());
* Cache<String, String> replicatedCache = manager.getCache("myReplicatedCache");
* </code>
