/**
* Loads the section $section from the config file $filename for
* access facilitated by nested object properties.
*
* If the section name contains a ":" then the section name to the right
* is loaded and included into the properties. Note that the keys in
* this $section will override any keys of the same
* name in the sections that have been included via ":".
*
* If the $section is null, then all sections in the ini file are loaded.
*
* If any key includes a ".", then this will act as a separator to
* create a sub-property.
*
* example ini file:
* [all]
* db.connection = database
* hostname = live
*
* [staging : all]
* hostname = staging
*
* after calling $data = new Enlight_Config_Format_Ini($file, 'staging'); then
* $data->hostname === "staging"
* $data->db->connection === "database"
*
* The $options parameter may be provided as either a boolean or an array.
* If provided as a boolean, this sets the $allowModifications option of
* Enlight_Config_BaseConfig. If provided as an array, there are three configuration
* directives that may be set. For example:
*
* $options = array(
* 'allowModifications' => false,
* 'nestSeparator' => ':',
* 'skipExtends' => false,
* );
*
* @param string $filename
* @param mixed $section
* @param boolean|array $options
* @throws Enlight_Config_Exception
* @return void
