Fix example_data.sh so that it points to the correct location of docker-entrypoint.sh

[kphurley]

When installing the project so I could hack on it, I ran into the issue described here: #84. I think this commit should fix and close that issue.

I noticed while doing a find for docker-entrypoint.sh that the location of this file inside of the container running the postgres process was tucked in /usr/local/bin. Changing the example_data.sh script to point to this location seems to correct this issue. After this change, I was able to seed the example data and run everything locally with no issues.

I also made a very minor change to the README to make running the server a tad more clear (there is no make run, I believe it should be make up 😄 )
