This should be usefull in achieving tree connection between objects.
For example - Family "Animals" -> defines some vars that are generic (height, weight etc..) and then you make Family "Dogs" that inherits Animals and it already contains the vars that Animals have + you can add more vars that are specific to Dogs. You can also continue that way.
Also -> you would create a function for example "Eat" In Animals and every inherited object would have "Eat" function. Therefore it would be helpfull really to create trees of objects without writing same code xx times.
This needs a fairly thorough review of the engine to investigate its feasibility. As such, we'll leave this idea as "needs review".
