Define an interface to pass signals to arbitrary subconverters

[wallscheid]

It may be worth directly extending the doubleConverter class to a "multiConverter" class in order to enable arbritrary converter combinations. Possible applications are:

• switched reluctance motors which stator winding system often consists of an integer number of independently supplied coils. Each coil is often fed by a half or full bridge.
• multi phase PMSM and IM: due to safety reasons and flexibility options, there is currently a trend to synchronous and induction motors with more than 3 phases. Typically, are 6-phase machines with 2xb6 inverters or also 5-phase motors with 5 independent half or full bridges.

Issue has been solved in inductionMotorFeature-branch by implementing suggestion (1) altogether with the MultiConverter functionality.

This issue should be closed after release of the branch contents.
