// There are often times in-game when we will want to change the values of a
// field in a character or object; most DIKU muds do this via a "set" command
// that simply has a list of all of the fields, and how to handle performing
// the set. However, because of our modular nature, it would be fairly 
// cumbersome to have all of the possible things to set in one big list. 
// Instead, we provide a way that modules can install new fields that can be
// set for rooms, objects, and mobiles.

// and the new value. If there are constraints on the applicable values that
// can be set, checker should be provided. It takes in the to-be-set value and
// makes sure it is OK, returning TRUE if it is and FALSE if it is not. The
// checker function should be of the form:
