coastlib's Issues

FentonWave class KeyError when initialized on Jupyter

Following the example from https://coastlib.readthedocs.io/en/latest/waves.html

from coastlib.waves import FentonWave
wave1 = FentonWave(wave_height=3, wave_period=6, depth=20)

produces the error as below:

KeyError                                  Traceback (most recent call last)

This was tested on a Jupyter notebook running Python Kernel 3.6 on azure notebooks.
