Added section from Eugene on report setting persistence.

Fixed typo.

+\subsection report_create_module_persistence Persisting your Report Module Configuration
+
+Both Java and Python report modules can have their configurations persisted to disk. In order to do so, the report module must do
+two things:
+<ol>
+<li> The report module must have a class that defines the configuration for the module (for example, org.sleuthkit.autopsy.report.modules.html.HTMLReportModuleSettings). This class
+must implement the ReportModuleSettings interface. Note that the ReportModuleSettings interface extends Serializable, therefore the report
+settings class must contain serialVersionUID variable:
+
+\code
+class HTMLReportModuleSettings implements ReportModuleSettings {
+    
+    private static final long serialVersionUID = 1L;
+    
+    HTMLReportModuleSettings() {
+    }
+    
+    @Override
+    public long getVersionNumber() {
+        return serialVersionUID;
+    }
+}
+\endcode
+
+<li>The report module implementation class (e.g. ReportHTML) must implement the following methods of the ReportModule interface:
+- getDefaultConfiguration()
+- getConfiguration()
+- setConfiguration(ReportModuleSettings settings)
+</ol>
+
+The use case scenario for this API when the configuration of a report module is occurring is as follows (using HTMLReport as example):
+<ol>
+<li>User clicks "Generate Reports" button in the Autopsy UI.
+<li>Report Configuration UI attempts to load the persisted reporting configuration from disk.
+<li>For each existing report module, if a persisted ReportModuleSettings (i.e. HTMLReportModuleSettings) configuration exists, Configuration UI calls HTMLReport.setConfiguration() with the persisted settings; Otherwise the Configuration UI calls HTMLReport.getDefaultConfiguration(), then HTMLReport.setConfiguration().
+<li>Configuration UI calls HTMLReport.getConfigurationPanel(). The report module loads the settings into its configuration panel and returns the panel.
+<li>Configuration UI presents the panel to the user. 
+<li>User interacts with the panel to modify the current settings of the report module.
+<li>Configuration UI calls HTMLReport.getConfiguration() and obtains the latest report module configuration.
+<li>Configuration UI persists the module settings.
+</ol>
