[522]26        "Model" is the skeleton of the Framsticks creature.
27        This object can be used for 2 purposes:
28        - you can build a creature from any supported Framsticks genotype
29        format
30        - or generate low level f0 genotype from existing construct.
[109]31
[522]32        In both cases you have access to geometry and neuron net data.
33        Using this standard class assures compatibility and good
34        integration with core Framsticks engine.
[109]35
[522]36        Model contains 3 kinds of objects:
37        - Parts (class Part).
38        - Joints (class Joint). Each Joint is connected with 2 Parts. (@see Joint::attachToParts()).
39        - Neurons (class Neuro). Neuron can have 0 or more inputs - other neurons. (@see Neuro::addInput()).
40        Each Neuron can be located on the physical structure, i.e. it can ba attached to Part or Joint
41        (@see Neuro::attachToPart(), Neuro::attachToJoint()).

428   An object of this class is created from a Model and returns the solids-type const Model& regardless of the source Model shape type.
429   For solids-type Models, the same source Model reference is returned.
430   For ball-and-stick-type Models, the new temporary Model is created (using Model::buildUsingSolidShapeTypes).
431   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:
[611]432
[546]433   void fun(const Model& input) // 'input' can be any shape type
434   {
[611]435   SolidsShapeTypeModel converted(input); // 'converted' contains either 'input' or the new solids-type Model created from 'input'
436   functionAcceptingSolidsTypeModel(converted); // operator const Model&() is called automatically because of the function signature
437   int n=converted.getModel().getPartCount(); // getting the const Model& explicitly (converted.getPartCount() would fail)
[546]438   }
