BaseNWBWidget

[bendichter]

I think we should have a BaseNWBWidget class that all widgets would extend. Something like:

class BaseNWBWidget():
    def __init__(self):
        self.controls = None
        self.figure = None

    @abstractmethod
    def update_figure(self):
        pass

then we can add any functionality that is shared across widgets to this base class. These functions might include exporting the figure as a vector graphic or using threading to manage parallel execution of widgets, etc.
