/**
* Get the config value associated for a given class and property
*
* This merges all current sources and overrides together to give final value
* todo: Currently this is done every time. This function is an inner loop function, so we really need to be caching heavily here.
*
* @param $class string - The name of the class to get the value for
* @param $name string - The property to get the value for
* @param int $sourceOptions - Bitmask which can be set to some combintain of Config::UNINHERITED, Config::FIRST_SET, and Config::EXCLUDE_EXTENSIONS.
* Config::UNINHERITED does not include parent classes when merging configuration fragments
* Config::FIRST_SET stops inheriting once the first class that sets a value (even an empty value) is encoutered
* Config::EXCLUDE_EXTRA_SOURCES does not include any additional static sources (such as extensions)
*
* Config::INHERITED is a utility constant that can be used to mean "none of the above", equvilient to 0
* Setting both Config::UNINHERITED and Config::FIRST_SET behaves the same as just Config::UNINHERITED
*
* should the parent classes value be merged in as the lowest priority source?
* @param null $result array|scalar - Reference to a variable to put the result in. Also returned, so this can be left as null safely. If you do pass a value, it will be treated as the highest priority value in the result chain
* @param null $suppress array - Internal use when called by child classes. Array of mask pairs to filter value by
* @return array|scalar - The value of the config item, or null if no value set. Could be an associative array, sequential array or scalar depending on value (see class docblock)
