18 This function is used to update what a property component is fixed to. 

19 For example, in the online solving, we want to update properties to their new values from the OPC UA server, and then re-solve the model. 

20 This saves us from having to re-create the model and re-fix all the properties every time. 

21 Args: 

22 - property_component (PropertyComponent): The property component to update. This can be retrieved from the PropertiesManager. 

23 - values (list[ValueWithUnits]): The new values to set the property component to. These could be a list of values with the IDAES unit attached too.
