Merge pull request #29 from chuckleb/master

Used a new method for detecting inside Docker container
Removed loop routine

Loop routine causing problems in clean Ubuntu installs. Will need to fix later.

Bug: https://github.com/STH-Dev/STHbench.sh/issues/30
Update STHbench-Dev012.11.sh

Added removeBenches() and consolidated the removals there. Called remove benches just after the echo "Uninstall benches" near the end of the file.

Some of the modules were not going back to the bench directory before processing the rm -rf commands. As a result, we were not removing them consistently.

Also, since they are removed out of the main modules that may make a few easier to loop.

We can not use this change if we do not want, but figured I would add.
Added header block comments
Create c-ray-looping-example

Just a quick snippet of code for user prompted looping using the c-ray portion of the STHbench script
