core.variables
Provides functions to create and manage variables.
There are two types of variables in App::RoboBot: message scope and global. Message scope variables persist only as long as it takes to process the current message and then they are destroyed. Global variables, however, persist indefinitely and are available across all channels on a single network. They may be re-used, changed, and undefined from anywhere on the network they were initialized, by anyone with permission to call the ``(set-global)`` or ``(unset-global)`` functions.
