SUMMATION

Syntax:  summation <start> <end> [multiplier]

This function calculates the value of a summation series.  Basically it sums
all the integers between the start and end numbers (including the start and end
numbers).  If no multiplier is specified, it is assumed to be 1.
e.g. summation 5 10
     Would return a result of 5 + 6 + 7 + 8 + 9 + 10 = 45.
