Create the Network.clone method

[dglmoore]

Description

Sometimes it's useful to be able to copy a network, particularly given we have mutating methods. As a motivating example, consider the global s_pombe network. If the user computes the its attractors, the result is cached inside of the global s_pombe object. This is bad hygiene!

Proposed API

class Network(LandscapeMixin, StateSpace):
    @abstractmethod
    def clone(self):
        pass

class WTNetwork(BooleanNetwork):
    def clone(self):
        return WTNetwork(np.copy(self.weights),
                         np.copy(self.thresholds),
                         np.copy(self.names),
                         self.theta)

Example Usage

>>> from neet.boolean.examples import s_pombe

>>> s_pombe_copy = s_pombe.clone()
<neet.boolean.wtnetwork.WTNetwork object at 0x...>
>>> s_pombe_copy.landscape()
<neet.boolean.wtnetwork.WTNetwork object at 0x...>

>>> s_pombe.landscape_data
None
>>> s_pombe_copy.landscape_data
<neet.landscape.LandscapeData object at 0x...>
