Install Issues on macOS 10.14 (Mojave)

I had some trouble building the C extensions on my laptop running macOS 10.14.3 and Xcode 10. Here is the error I saw:

poma:wobble bfulton$ python setup.py develop
/Users/bfulton/anaconda3/lib/python3.6/site-packages/h5py/__init__.py:34: FutureWarning: Conversion of the second argument of issubdtype from `float` to `np.floating` is deprecated. In future, it will be treated as `np.float64 == np.dtype(float).type`.

I found a solution here: https://blog.driftingruby.com/updated-to-mojave/

In summary, you need to install the SDK headers for 10.14 separately:

open /Library/Developer/CommandLineTools/Packages/

Run the package macOS_SDK_headers_for_macOS_10.14.pkg

Try to build again: cd wobble; python setup.py install
