* The key is used to identify the property that will be accessible with the `get` and
* 'dangerously_set_global_context' method, e.g. `$context->get( 'event_display', 'list' );`.
* The locations is a list of locations the context will search, top to bottom, left to right, to find a value that's
* not empty or the default one, here's a list of supported lookup locations:
*
* request_var - look into $_GET, $_POST, $_PUT, $_DELETE, $_REQUEST.
* query_var - get the value from the main WP_Query object query vars.
* query_prop - get the value from a property of the main WP_Query object.
* tribe_option - get the value from a Tribe option.
* option - get the value from a database option.
* transient - get the value from a transient.
* constant - get the value from a constant, can also be a class constant with <class>::<const>.
* global_var - get the value from a global variable
* static_prop - get the value from a class static property, format: `array( $class, $prop )`.
* prop - get the value from a tribe() container binding, format `array( $binding, $prop )`.
* static_method - get the value from a class static method.
* method - get the value calling a method on a tribe() container binding.
* func - get the value from a function or a closure.
* filter - get the value by applying a filter.
* location_func - get the value by applying a callback to the value of a location.
*
* For each location additional arguments can be specified:
* orm_arg - if `false` then the location will never produce an ORM argument, if provided the ORM arg produced bye the
* location will have this name.
* orm_transform - if provided the value of the location will be obtained by passing it as an argument to a callable.
*
* As the Context locations increase in number it would be impractical to define them inline here.
* The locations will be loaded by the `Tribe__Context::populate_locations` method from the `Context/locations.php`
