Added Quick Start intro

  There is a separate JMX component for Derby in Jira. Search for [http://issues.apache.org/jira/secure/IssueNavigator.jspa?reset=true&mode=hide&pid=10594&sorter/order=DESC&sorter/field=priority&resolution=-1&component=12312171
issues with the JMX component] to get an updated list of all JMX related issues.

+ Derby's JMX features are automatically available when Derby is started in a Java Virtual
Machine (JVM) supporting the [http://java.sun.com/j2se/1.5.0/docs/guide/management/overview.html#mxbeans
platform MBean Server]. This includes JVMs supporting J2SE 5.0, Java SE 6, or newer. Derby's
JMX features are not available when using J2SE 1.4.2 or Java ME (as per March 2008).
+ You start Derby by loading Derby's embedded driver. If you are using Derby's Network Server,
the embedded driver is automatically loaded in the server JVM when the server is started.
+ Basically, Derby's JMX features consist of a set of MBeans (Managed Beans) and their attributes
and operations. MBean implementations instrument one or more parts of a running Derby system,
potentially giving you real-time access to Derby-specific information from a host of your
choice. The word ''potentially'' here indicates that JMX access may depend on how you configure
your JVM and (for example) Derby's security features.
+ Note that if you are unfamiliar with JMX technology, it may be a good idea to take a look
at some of the references provided [#Resources above] before you continue. 
+ You may access Derby's MBeans using for example an existing JMX client utility, such as
JConsole, or programmatically by writing your own Java code utilizing JMX.
