Lines 81 to 116 in e2fa122

	Defining a MIMO-converter:
	>>> from oemof import solph
	>>> bgas = solph.buses.Bus(label='natural_gas')
	>>> bcoal = solph.buses.Bus(label='hard_coal')
	>>> bel = solph.buses.Bus(label='electricity')
	>>> bheat = solph.buses.Bus(label='heat')
	>>> trsf = solph.components.Converter(
	... label='pp_gas_1',
	... inputs={bgas: solph.flows.Flow(), bcoal: solph.flows.Flow()},
	... outputs={bel: solph.flows.Flow(), bheat: solph.flows.Flow()},
	... conversion_factors={bel: 0.3, bheat: 0.5,
	... bgas: 0.8, bcoal: 0.2})
	>>> print(sorted([x[1][5] for x in trsf.conversion_factors.items()]))
	[0.2, 0.3, 0.5, 0.8]
	>>> type(trsf)
	<class 'oemof.solph.components._converter.Converter'>
	>>> sorted([str(i) for i in trsf.inputs])
	['hard_coal', 'natural_gas']
	>>> trsf_new = solph.components.Converter(
	... label='pp_gas_2',
	... inputs={bgas: solph.flows.Flow()},
	... outputs={bel: solph.flows.Flow(), bheat: solph.flows.Flow()},
	... conversion_factors={bel: 0.3, bheat: 0.5})
	>>> trsf_new.conversion_factors[bgas][3]
