(e.g. PointLight in the light family). Some families of classes has no
default, so they cannot be instantiated this way.
light light_name : class WarnLight
{
translate <0, 1, 0>
point_at <0, 0, 0>
color CWhite
}
Referred class should be a built-in class, or a registered plugin.
light light_name : extends another_light_name
{
intensity 100
}
New object will be a copy of referred object, with aditional changes
