/**
* Factory for Zend_Db_Adapter_Abstract classes.
*
* First argument may be a string containing the base of the adapter class
* name, e.g. 'Mysqli' corresponds to class Zend_Db_Adapter_Mysqli. This
* name is currently case-insensitive, but is not ideal to rely on this behavior.
* If your class is named 'My_Company_Pdo_Mysql', where 'My_Company' is the namespace
* and 'Pdo_Mysql' is the adapter name, it is best to use the name exactly as it
* is defined in the class. This will ensure proper use of the factory API.
*
* First argument may alternatively be an object of type Zend_Config.
* The adapter class base name is read from the 'adapter' property.
* The adapter config parameters are read from the 'params' property.
*
* Second argument is optional and may be an associative array of key-value
* pairs. This is used as the argument to the adapter constructor.
*
* If the first argument is of type Zend_Config, it is assumed to contain
* all parameters, and the second argument is ignored.
*
* @param mixed $adapter String name of base adapter class, or Zend_Config object.
* @param mixed $config OPTIONAL; an array or Zend_Config object with adapter parameters.
* @return Zend_Db_Adapter_Abstract
* @throws Zend_Db_Exception
