/**
 * TDbParameterModule class
 *
 * This loads application parameters from a database.  It adds the
 * {@see \Prado\Util\Behaviors\TMapLazyLoadBehavior} to Application Parameters when the
 * {@see setAutoLoadField} is set.  The key and name fields, table,
 * autoload field, and autoload values (both true and false values)
 * are parameterized.  Set them to your application specific values.
 *
 * The following will load the options from a WordPress Database:
 * ```xml
 *		<module id="dbparams" class="Prado\Util\TDbParameterModule"
 * ConnectionID="DB" KeyField="option_name" ValueField="option_value" TableName="wp_options" Serializer="php"
 * autoLoadField="autoload" autoLoadValue="'yes'" autoLoadValueFalse="'no'"/>
 * ```
 *
 * This allows for setting and removal of application parameters
 * into and from the database through {@see set} and
 * {@see remove}, respectively. Arrays and Objects are
 * serialized.  The specific serializer can be chose to be 'php',
 * 'json', or provide your own function or callable.  Default to 'php'.
 *
 * setting {@see setSerializer} to your own function that has the
 * following format:
 * ```php
 *		function mySerializerFunction($data, $encode) {...}
 * ```
 * If $encode is true, then encode, otherwise decode, to text.
 *
 * When {@see getCaptureParameterChanges} is true, the default,
 * then this will route any changes to the Application Parameters
 * after TPageService::onPreRunPage back to the TDbParameterModule
 * and be saved to the database.  This captures any changes when
 * done by the page or user.  These changes are restored when
 * this module is loaded again.
 *
 * When TPermissionsManager is a module in your app, there is one permission
 * to control user access to its function:
 *  - TDbParameterModule::PERM_PARAM_SHELL 'param_shell' enables the shell command to index, get and set database parameters.
 *
 * The role and rule management functions only work when the TDbParameter Module is specified.
 * The following gives user "admin" and all users with "Administrators" role the
 * permission to access permissions shell and its full functionality:
 * ```xml
 *   <permissionrule name="param_shell" action="allow" users="admin" />
 *   <permissionrule name="param_shell" action="allow" roles="Administrators" />
 * ```
