Containerized

This version of Path To Adventure adds a Containerfile to build a
containerized version, so that students can play even when they don't
have the ability to use sudo to perform arbitrary commands.

Additionally, the script used to setup the game has been refactored into
a number of parts to make it easier for others to contribute.

Finally, this version includes bash-preexec, from
https://github.com/rcaloras/bash-preexec which will allow for
instantaneous responses to happen. Currently, only one rudimentary
instantaneous response has been coded, but others will be added in the
future.

v0.2.3

This release uses overlayfs to allow for replayability. It also creates a link in the root directory to the world so that paths like /World/cottage/treasure_chest will work.

v0.2.2

This changes the behavior where playing in easymode will automatically print the README file whenever you change into a directory that contains a README file. You can still have this behavior, if you set AUTOREADME=1.

v0.2.1

This just fixes a typo in the PROMPT_COMMAND to use [[ instead of [ for the test command.

v0.2.0

This release changes the directory structure so that the cottage directory is contained within a world directory, which also contains all the other locations. I think I have updated everything that this change affects, but I might have missed something. This makes more sense than the previous version in which the cottage directory contained a directory called outside that had the world in it.

This release also updates the .welcome.sh script that is run at the beginning of the game to make sure that the world is configured correctly when you start it. This means that you can't really leave and come back to the game without some of your progress possibly being reset.

Also, now hard mode looks a little more intense.

v0.1.0

This new version has a scoring script that works really well, along with:

• an experience starting the game to get players into the game.
• a new help command that will list the only the commands that are useful for the game.
• the game starts it's own shell to run in, so it doesn't pollute the environment it gets run in.
• check the README.md for instructions on running the game.
