/**
    "Model" is the skeleton of the framsticks creature.
    This object can be used for 2 purposes:
     - you can build a creature from any supported framsticks genotype
    format
     - or generate low level f0 genotype from existing construct.

    In both cases you have access to geometry and neuron net data.
    Using this standard class assures compatibility and good
    integration with core framsticks engine.

    Model contains 3 kinds of objects:
    - Parts (class Part).
    - Joints (class Joint). Each Joint is connected with 2 Parts. (@see Joint::attachToParts()).
    - Neurons (class Neuro). Neuron can have 0 or more inputs - other neurons. (@see Neuro::addInput()).
      Each Neuron can be located on the physical structure, i.e. it can ba attached to Part or Joint
      (@see Neuro::attachToPart(), Neuro::attachToJoint()).
