Investigate security issues

[aaron97neu]

Allowing random users to execute code on your server should be met with pretty heavy skepticism from a security perspective in most cases. Not only is that being done here, but the user has unlimited access to all default python libraries (including those that allow interaction with file system and os), and in the case of ibnkhaldun, potentially with root access. This is incredibly dangerous if we wish to run a publicly accessible server.

This will likely spawn sub issues as we identify specific security issues.
Potential fixes:

• Do not allow users to call internal functions
• Restrict available libraries to only those necessary
• Run code clientside (is there a js library for this? Is this feasible)
