Upload dask-searchCV notebook

[rdvelazquez]

This PR continues on PR #98.

The notebook shows the implementation of dask-searchcv to speed up the pipeline and allow for implementing PCA in cross-validation. This PR is the first step in addressing Issue #94 ... The next step will be to implement dask-searchcv in the main notebooks after #93 is merged.

What version of dask-searchcv did you use? We will need to add this to our environment.

[rdvelazquez]

I followed the instructions from the dask/dask-searchcv github page:

# Install with conda
$ conda install dask-searchcv -c conda-forge

When I list my packages installed in anaconda it shows :

dask 0.14.3
dask-searchcv 0.0.2

We will need to add this to our environment.

Should I open a new pull-request to add dask-searchcv to environment.yml and to the main notebooks or should that be part of this PR? Also, I don't know if the notebook currently in this PR is really a necessary addition (it was more just my own evaluation of dask-searchcv) so I'm fine with leaving this notebook out and just focusing on implementing dask-searchCV in the main notebooks. Just let me know.

I think it's appropriate in explore. I'll merge this now. You can do another PR to implement dask-searchcv in the main notebooks and add it to the environment. I'd suggest waiting until we merge #100 and then starting your PR from there.
