Extending the generator by providing additional sources of data

There is an easy mechanism for extending the test message generator so that it can get data from other sources: the org.eclipse.soc.ohftest plugin defines an extension point called batchDataSources. In order to use this extension point, a user needs to create a class which implements the IBatchDataSource interface, and a factory class for this data source (a class that implements the IBatchDataSourceFactory), which needs to be referenced in the plugin.xml file of the plugin that will be providing the extension.
