Quickly check whether model is consistent

    Return true if the model is consistent. If it is only necessary to know
    whether a model is consistent, this function is fast as it will return
    the result as soon as it finds a single inconsistent reaction.

    Args:
        model: :class:`MetabolicModel` to solve.
        epsilon: Flux threshold value.
        solver: LP solver instance to use.
