    @class      MPSumFunctionTerm
    @abstract   Represents and evaluates a <code>@link
                //apple_ref/occ/cl/MPSumFunction@/link</code>.
 
    @discussion A sum function evaluates its sum term <code>n</code> times. How
                often it actually is evaluated depends on the boundary
                expressions (start and target). Both are inclusive.
 
                A sum function also features a variable that contains the current
                value of the iteration. The variable is defined in the start
                expression and incremented by <code>1</code> after every
                iteration.
