README initial environment instructions no longer valid

[john-aws]

The README suggests creating a conda environment as follows:

conda create  --DeepRule python-course --file DeepRule.txt

but this fails on recent conda installations (e.g. 4.10.3) with:

usage: conda [-h] [-V] command ...
conda: error: unrecognized arguments: --DeepRule

At a guess, this should now be:

conda create  --name DeepRule --file DeepRule.txt

Also, the subsequent environment activation step should potentially change from:

source activate DeepRule

to the following:

conda activate DeepRule
