A base class representing a two-state muscle-tendon actuator.
It adds activation and fiber-length states and dynamics to the Muscle class, but does not implement all of the necessary methods, so it is abstract as well. The path information for a muscle is contained in the Muscle class, and the force-generating behavior should be defined in the derived classes.
(Based on earlier work by Peter Loan and Frank C. Anderson.)

Create a new heap-allocated copy of the concrete object to which this Object refers.
It is up to the caller to delete the returned object when no longer needed. Every concrete object deriving from Object implements this pure virtual method automatically, via the declaration macro it invokes (e.g., OpenSim_DECLARE_CONCRETE_OBJECT()). Note that the concrete class overrides modify the return type to be a pointer to the concrete object; that still overrides the base class method because the return type is covariant with (that is, derives from) Object.

Subclasses must implement this method to compute the forces that should be applied to bodies and generalized speeds.

If a model component has allocated any continuous state variables using the addStateVariable() method, then computeStateVariableDerivatives() must be implemented to provide time derivatives for those states.
Override to set the derivatives of state variables added to the system by this component. (also see extendAddToSystem()). If the component adds states and computeStateVariableDerivatives is not implemented by the component, an exception is thrown when the system tries to evaluate its derivatives.
Implement like this:
For subclasses, it is highly recommended that you first call Super::computeStateVariableDerivatives(state) to preserve the derivative computation of the parent class and to only specify the derivatives of the state variables added by name. One does have the option to override all the derivative values for the parent by accessing the derivatives by their state variable name. This is necessary, for example, if a newly added state variable is coupled to the dynamics (derivatives) of the states variables that were added by the parent.
Reimplemented from OpenSim::Component.

overrideprotectedvirtual |
Add appropriate Simbody elements (if needed) to the System corresponding to this component and specify needed state resources.
extendAddToSystem() is called when the Simbody System is being created to represent a completed system (model) for computation. That is, connect() will already have been invoked on all components before any addToSystem() call is made. Helper methods for adding modeling options, state variables and their derivatives, discrete variables, and cache entries are available and can be called within extendAddToSystem() only.
Note that this method is const; you may not modify your model component or the containing model during this call. Any modifications you need should instead be performed in finalizeFromProperties() or at the latest connect(), which are non-const. The only exception is that you may need to record access information for resources you create in the system, such as an index number. For most Components, OpenSim base classes either provide convenience methods or handle indices automatically. Otherwise, you must declare indices as mutable data members so that you can set them here.
If you override this method, be sure to invoke the base class method at the beginning, using code like this:
This method assumes that this Component's addToSystem will be invoked before its subcomponents. If you need your subcomponents to be added to the system, first (e.g. require of a Force to be anchored to a SimTK::MobilizedBody specified by subcomponents) then you must implement: extendAddToSystemAfterSubcomponents(). It is possible to implement both method to add system elements before and then after your subcomponents have added themselves. Caution is required that Simbody elements are not added twice especially when order is unimportant.

Transfer property values or other state-independent initial values into this component's state variables in the passed-in state argument.
This is called after a SimTK::System and State have been created for the Model (that is, after extendAddToSystem() has been called on all components). You should override this method if your component has properties (serializable values) that can affect initial values for your state variables. You can also perform any other state-independent calculations here that result in state initial conditions.
If you override this method, be sure to invoke the base class method first, using code like this:
state | The state that will receive the new initial conditions. |

Adjust the properties of the muscle after the model has been scaled.
The optimal fiber length and tendon slack length are each multiplied by the ratio of the current path length and the path length before scaling.

Update this component's property values to match the specified State, if the component has created any state variable that is intended to correspond to a property.
Thus, state variable values can persist as part of the model component and be serialized as a property.
If you override this method, be sure to invoke the base class method first, using code like this:
state | The State from which values may be extracted to set persistent property values. |

Returns the class name of the concrete Object-derived class of the actual object referenced by this Object, as a string.
