Detailed Description

Takes a workspace as input and sums all of the spectra within it maintaining the existing bin structure and units.

The result is stored as a new workspace containing a single spectra.

Required Properties:

InputWorkspace - The name of the Workspace2D to take as input
OutputWorkspace - The name of the workspace in which to store the result

Optional Properties (assume that you count from zero):

StartSpectrum - Workspace index number to integrate from (default 0)
EndSpectrum - Workspace index number to integrate to (default max)
IncludeMonitors - Whether to include monitor spectra in the sum (default yes)
