Attribute ``remove`` does not exist

[izkgao]

I followed the guide on the documentation, but an error occurred.

AttributeError Traceback (most recent call last)

1 flux = np.ones(3)
2 wave = np.array([5., 2.5, 1.25])
----> 3 extinction.remove(extinction.ccm89(wave, 1.0, 3.1), flux)

AttributeError: module 'extinction' has no attribute 'remove'

remove was added in the development version but hasn't yet been released. In the meantime, extinction.apply(extinction.ccm89(wave, -1.0, 3.1), flux) is equivalent.
