Spring Refactor and Implementation
Created the following files to support Spring: applicationContext.xml
The following classes were modified to support Spring setter based
dependancy injection: ClusterManager, IsiSizerSocketManager,
IsiSizerServer, CreateDeleteClusterServiceJdbcImpl,
ICreateDeleteClusterService, ILoadSaveClusterService,
INodeConfigurationService, NodeConfigurationServiceJdbcImpl, ViewDriver,
and IsiSizerJFrameController

All corresponding test cases modified to support Spring.

The following classes and files have been removed as they are
unnecessary or unused after implementing Spring: AppProperties.xsd,
app.properties, app.properties.xml, IsiSizerDaoJdbcImpl.java,
IService.java, DaoFactory.java, ServiceFactory.java,
PropertyManager.java, SAXPropertyManager.java, DaoFactoryTest.java, and
ServiceFactoryTest.java
