Detailed Description

Divide performs the division of two input workspaces.

It inherits from the Algorithm class, and overrides the init() & exec() methods.

Required Properties:

LHSWorkspace - The name of the workspace
RHSWorkspace - The name of the workspace
OutputWorkspace - The name of the workspace in which to store the division data
