// This module allows key/value pairs to be dynamically created on characters,
// objects, and rooms. Values can be strings, integers, or doubles. If a value
// is called for in the wrong type (e.g. you're trying to get a string as an 
// integer) the module will automagically handle the conversion. Variable types
// default to ints.
