A unit consisting of a number of other units.
Composite units are defined by a unit expression with multiple units. Composite units often have an alias unit associated with them, as they do not have a reference name on their own. For example, a joule is defined as an alias defined in relation to a composite unit defined as "Newton * meter".
The names of composite units are only used to reference the unit in definitions of other units. They can not be used in expressions.
Composite units are defined as a composition of units. The units, with prefixes and exponents, can either be added one by one with add() or parsed from an expression (ex. "cm^3/g) with setBaseExpression().
