/**
* Container for default property constants.
* <p/>
* This class also provides static utility methods for
* {@link Properties} and <code>Settings</code> objects.
* <p/>
* To add new properties to the jTDS driver, do the following:
* <ol>
* <li>Add <code>prop.<em>foo</em></code> and <code>prop.desc.<em>foo</em></code>
* properties to <code>Messages.properties</code>.</li>
* <li>Add a <code>static final</code> default field to {@link DefaultProperties}.</li>
* <li>Update {@link #addDefaultProperties(java.util.Properties)} to set the default.</li>
* <li>Update <code>Driver.createChoicesMap()</code> and
* <code>DriverUnitTest.test_getPropertyInfo_Choices()</code> if the property
* has a specific set of inputs, e.g., "true" and "false", or "1" and "2".</li>
* <li>Update <code>Driver.createRequiredTrueMap()</code> and
* <code>DriverUnitTest.test_getPropertyInfo_Required()</code> if the property
* is required.</li>
* <li>Add a new test to <code>DefaultPropertiesTestLibrary</code> for the new
* property.</li>
* </ol>
