Interface that defines parameters for error control

## Information

This is an interface that defines parameters used for error control.

Dymola does error control on state variables, such as temperature, pressure and species concentration. Flow variables such as `m_flow` are typically not checked during the error control. This can give large errors in flow variables, as long as the error on the volume's state variables that are coupled to the flow variables is small. Obtaining accurate flow variables can be achieved by imposing an error control on the exchanged mass, which can be defined as

      dm/dt = m_flow.

By setting `forceErrorControlOnFlow = true`, such an equation is imposed by models that extend this class.
