documentation.py must use new parameters class

[manuelpastor]

Documentation class must not load directly parameters.yaml, but instantiate a flame/parameters.py class, load existing parameters using param.loadYaml(endpoint_name, endpoint_version) and use getValue

from flame.parameters import Parameters

param = Parameters()
success, message = param.loadYaml(model, 0)
