Model changes.

Model changes are structural changes to the model structure. Changes of values and initial conditions are encoded via the changes instead.

Structural change to a model.

clamp_species staticmethod 

clamp_species(r, species_id, formula=True, speed=10000.0)

Clamp/free species to certain value or formula.

This is only an approximative clamp, i.e. not working instantenious. Depending on the model kinetics different speed settings are required. FIXME: time cannot be used in formula due to https://github.com/sys-bio/roadrunner/issues/601 FIXME: concentrations and amounts are not handled (uses native species setting i.e., amount or concentration definition.
