/**
*
* Starts Solar: loads configuration values and and sets up the environment.
*
* Note that this method is overloaded; you can pass in different
* value types for the $config parameter.
*
* * `null|false` -- This will not load any new configuration values;
* you will get only the default [[Solar::$config]] array values defined
* in the Solar class.
*
* * `string` -- The string is treated as a path to a Solar.config.php
* file; the return value from that file will be used for [[Solar_Config::load()]].
*
* * `array` -- This will use the passed array for the [[Solar_Config::load()]]
* values.
*
* * `object` -- The passed object will be cast as an array, and those
* values will be used for [[Solar_Config::load()]].
*
* Here are some examples of starting with alternative configuration parameters:
*
* {{code: php
* require_once 'Solar.php';
*
* // don't load any config values at all
* Solar::start();
*
* // point to a config file (which returns an array)
* Solar::start('/path/to/another/config.php');
*
* // use an array as the config source
* $config = array(
* 'Solar' => array(
* 'ini_set' => array(
* 'error_reporting' => E_ALL,
* ),
* ),
* );
* Solar::start($config);
*
* // use an object as the config source
* $config = new StdClass;
* $config->Solar = array(
* 'ini_set' => array(
* 'error_reporting' => E_ALL,
* ),
* );
* Solar::start($config);
* }}
*
* @param mixed $config The configuration source value.
*
* @return void
*
* @see Solar::cleanGlobals()
