26/**
27        "Model" is the skeleton of the Framsticks creature.
28        This object can be used for 2 purposes:
29        - you can build a creature from any supported Framsticks genotype
30        format
31        - or generate low level f0 genotype from existing construct.
32
33        In both cases you have access to geometry and neuron net data.
34        Using this standard class assures compatibility and good
35        integration with core Framsticks engine.
36
37        Model contains 3 kinds of objects:
38        - Parts (class Part).
39        - Joints (class Joint). Each Joint is connected with 2 Parts. (@see Joint::attachToParts()).
40        - Neurons (class Neuro). Neuron can have 0 or more inputs - other neurons. (@see Neuro::addInput()).
41        Each Neuron can be located on the physical structure, i.e. it can ba attached to Part or Joint
42        (@see Neuro::attachToPart(), Neuro::attachToJoint()).

456/**
457   An object of this class is created from a Model and returns the solids-type const Model& regardless of the source Model shape type.
458   For solids-type Models, the same source Model reference is returned.
459   For ball-and-stick-type Models, the new temporary Model is created (using Model::buildUsingSolidShapeTypes).
460   Useful for making the solids-only code work for both solids Models and ball-and-stick Models, without if's and special cases, like in this example:
461
462   void fun(const Model& input) // 'input' can be any shape type
463   {
464   SolidsShapeTypeModel converted(input); // 'converted' contains either 'input' or the new solids-type Model created from 'input'
465   functionAcceptingSolidsTypeModel(converted); // operator const Model&() is called automatically because of the function signature
466   int n=converted.getModel().getPartCount(); // getting the const Model& explicitly (converted.getPartCount() would fail)
467   }
