convenient way to handle parameters during reaction building

[zoltuz]

It would be nice to have a get_parameters() (or similar) function that accepts a list of parameter strings (with the same part_id, and mechanism) and returns a dictionary of parameters.

p =  component.get_parameters(['ktl','kb','ku','length'], part_id = part_id, mechanism = self)

#RNAP DNA Binding
r1 = Reaction.from_massaction([transcript, self.ribosome], [bound_complex], k_forward = p.kb, k_reverse = p.ku)
#Transcription
r2 = Reaction.from_massaction(self.fuels + [bound_complex], self.fuels + [transcript, self.ribosome, protein],
    k_forward = parameter_to_value(p.ktl.value)/parameter_to_value(p.length))
#Fuel consumption
r3 = Reaction.from_massaction(self.fuels + [bound_complex], [bound_complex]+self.wastes, k_forward = p.ktl)

Orignal code

ktl =  component.get_parameter("ktl", part_id = part_id, mechanism = self)
kb = component.get_parameter("kb", part_id = part_id, mechanism = self)
ku = component.get_parameter("ku", part_id = part_id, mechanism = self)
L = component.get_parameter("length", part_id = part_id, mechanism = self)

#RNAP DNA Binding
r1 = Reaction.from_massaction([transcript, self.ribosome], [bound_complex], k_forward = kb, k_reverse = ku)
#Transcription
r2 = Reaction.from_massaction(self.fuels + [bound_complex], self.fuels + [transcript, self.ribosome, protein],
    k_forward = parameter_to_value(ktl.value)/parameter_to_value(L))
#Fuel consumption
r3 = Reaction.from_massaction(self.fuels + [bound_complex], [bound_complex]+self.wastes, k_forward = ktl)

yeah that is a nice feature. Will definitely add it to a future update!
