[ModelicaSystem] setInput() - handly input data as list of tuples

This method is used to set input values. It can be called with a sequence of input name and assigning corresponding values as arguments as show in the example below. Compared to other set*() methods this is a special case as value could be a list of tuples - these are converted to a string in _prepare_input_data() and restored here via ast.literal_eval().
