function view_alias_next_tuple in View Alias 7

Return the next set of objects to be processed. That is, if you have two arguments in the view, tid and tid_1, where there there 3 terms possible in argument tid and 2 in tid_1, then return the next item in the list:

• 0,0
• 1,0
• 2,0
• 0,1
• 1,1
• 2,1

If you have three arguments, return a copy of this with 0..n in the third column.

• 0,0,0
• 1,0,0
• 2,0,0
• 0,1,0
• 1,1,0
• 2,1,0 ...
• 0,0,n
• 1,0,n
• 2,0,n
• 0,1,n
• 1,1,n
• 2,1,n
