Masterpress 1.3.6 is a compatibility release. It resolves an edge case with shared fieldsets not working for MySQL 8 when the fieldset is limited to more than 1 post type or taxonomy or excluding any post types or taxonomies.
Implements the PHP magic method __get called when an unknown property is accessed. In this case, the method first tries to access a value via the WOOF_Wrap::get method, and if nothing is found, will then try to access a set with the given name. This is the favoured way to access field sets in your templates, as it the most user friendly and concise way to write template code.
WOOF_Wrap::get is favoured first since this allows mixin methods (see: WOOF::mixin) to take priority over field sets, since we can always access a set via the standard set if a mixin method shares the name of a set, but not the other way round.
Note: this method is not called directly, it is called automatically by PHP if there is no property with the given name (accessed through the arrow operator on the object).
