CWholePage* CVotePageBuilder::Build()
Author: Mark Howitt
Created: 26/08/2003
Inputs: -
Outputs: -
Returns: -
Purpose: Creates the voting pages
URL Inputs :-
Action - "Add" for add responce
"Create" to get the create vote page
"New" to create and process a new vote
"Finish" to display final page.
"view" to view a given vote
VoteID - The ID of the voting poll for the vote
Type - The Type of object the vote belongs to
ObjectID - The page ID which the vote lives on. This is used to
navigate back to the page after finishing or canceling.
Response - The actual Response from the vote. "0" = Against "1" = For.
ShowUser - A Flag to state wether the user has requested to be
hidden or shown in the supporters table.
VoteName - The name of a new vote.
ClosingDate - A Date of when a vote is to close.
UseYesNo - A flag to see if we want a simple yes no voting system
