Model of a generic impedance

## Information

Model of an impedance. This model can be used to represent any type of resistive, inductive or capacitive load.

Note that the power consumed by the impedance model will drecrease if its voltage decreases.

The model of the impedance is

V = Z i,

where Z = R + j X is the impedance. The value of the resistance R and the reactance X depend on the type of impedance. Different types of impedances can be selected using the boolean parameters `inductive`, `use_R_in`, `use_L_in`, and `use_C_in`. See BuildingSystems.Electrical.Interfaces.Impedance for more details.

## Revisions

- May 26, 2016, by Michael Wetter:
  Moved function call to `PhaseSystem.thetaRef` out of derivative operator as this is not yet supported by JModelica.
- March 30, 2015, by Michael Wetter:
  Made `PhaseSystem` and `terminal` replaceable. This was detected by the OpenModelica regression tests.
- September 4, 2014, by Michael Wetter:
  Revised documentation.
- August 5, 2014, by Marco Bonvini:
  Revised documentation.
- January 2, 2012, by Michael Wetter:
  First implementation.
