	Defines a new unit. The symbol is the name of the unit and must begin with a percent sign % to distinguish it from a variable name. The expression defines the unit in terms of units already known to iMath. If this expression contains data types apart from units, powers of units, numerics, or constants already known to iMath, a warning is issued, but the unit definition is created anyway.
