WmPublic. Adds a list of integers (represented in a String list) and returns the sum.

Make sure the strings that are passed to the service in numList are in a locale-neutral format (that is, using the pattern -####.##). Passing locally formatted strings may result in unexpected results. For example, calling pub.math:addFloats in a German locale with the arguments 1,23 and 2,34 will result in the value 357, not 3.57 or 3,57.
