added AbstractMBean (base class for all Sigar MBeans)
added MBean impls for Cpu, CpuPerc, CpuInfo and Mem added SigarRegistry MBean (auto-registers a default set of MBeans when registered to/created by an MBeanServer)

/**

* <p>Registry of all Sigar MBeans. Can be used as a convenient way to invoke
|
||||
* Sigar MBeans at a central point. This brings a bunch of advantages with
|
||||
* it:</p>
|
||||
*
|
||||
* <ul>
|
||||
* <li>This class can be instantiated and registered to the MBean server by
|
||||
* simply calling {@link MBeanServer#createMBean(String, ObjectName)},
|
||||
* resulting in the automatic creation of all known default Sigar MBeans such
|
||||
* as CPU and memory monitoring beans.</li>
|
||||
* <li>Any Sigar MBean spawned by an instance of this class will use the same
|
||||
* {@link org.hyperic.sigar.Sigar} instance, saving resources in the
|
||||
* process.</li>
|
||||
* <li>When this instance is deregistered from the MBean server, it will
|
||||
* automatically deregister all instances it created, cleaning up behind
|
||||
* itself.</li>
|
||||
* </ul>
|
||||
*
|
||||
* <p>So using this class to manage the Sigar MBeans requires one line of code
|
||||
* for creation, registration and MBean spawning, and one line of code to shut
|
||||
* it all down again.</p>
