In order to fix#11408, this swaps `joblib` and `_joblib`. It however, allows users to access joblib's `Memory` or `Parallel` functionality without accessing `sklearn.externals._joblib` by importing `Memory`, `Parallel`, etc. into `sklearn.utils`.
* Ensure that the number of angles is integer
* Fix plot_tomography_l1_reconstruction.py
Error was: TypeError: 'numpy.float64' object cannot be interpreted as an integer.
[doc build]
* DOC examples with correct notebook style
* Modifications in examples/ to avoid unwanted notebook style
* Remove last notebook style example
* Space formatting to avoid notebook style
* DOC updated plot_stock_market.py to use Google Finance
The implementations is intentionally very basic not to distract the users
from the example. Specifically unlike ``quotes_historical_yahoo_ochl`` it
does not cache downloaded data.
I also had to remove some symbols because the have no data on Google for
the specified date interval. These are WBA, LMT, KFT and MTU.
Closes#8899
* DOC removed plot_stock_market.py from expected failing examples
* Addressed review comments
