add_constructor
Description:
public Value add_constructor (string? name, owned ClassConstructorCb callback, Type return_type)
Add a constructor to this.
If name is null, the class name will be used. When <function>new</function> is used
with the constructor or jsc_value_constructor_call is called, callback is invoked receiving a
GenericArray of Value
<!-- -->s as arguments and user_data as the last parameter. When the constructor object is cleared in the
Class context, destroy_notify is called with user_data
as parameter.
This function creates the constructor, which needs to be added to an object as a property to be able to use it. Use set_value to make the constructor available in the global object.
Note that the value returned by callback is adopted by this, and the
DestroyNotify passed to
register_class is responsible for disposing of it.
Parameters:

| callback |
a ClassSetPropertyCb to be called to create an instance of this |
| return_type |
the Type of the constructor return value |
