Convenient static methods for enumeration serialization to string.
Enumerations have a set of utility methods to better represent on serialisation/deserialization.
Enumerations could be converted to string using its definition on GLib.EnumClass, by taking its nick name
directly or converting to its camel case representation.
Any enumeration value type in a <code>GLib.Object</code>'s property could be deserialized from its definition given on
GLib.EnumClass (name and nick) or from its camel case representation.
