Proposed update to datagrid library

[Bob Sneidar]

Not nearly as sexy, but it does what I need it to. 

getProp dgNextIndex [tIndex]
   put the dgIndexes of me into tIndexes
   put itemOffset(tIndex, tIndexes) into tItem
   
   if tItem = the the number of items of tIndexes then
      put item tItem of tIndexes into tIndex
   else 
      put item tItem +1 of tIndexes into tIndex
   end if
   
   return tIndex
end dgNextIndex

getProp dgPrevIndex [tIndex]
   put the dgIndexes of me into tIndexes
   put itemOffset(tIndex, tIndexes) into tItem
   
   if tItem = 1 then
      put item tItem of tIndexes into tIndex
   else 
      put item tItem -1 of tIndexes into tIndex
   end if
   
   return tIndex
end dgPrevIndex

Then find the index returned by dgIndexOfLine in the dgIndexes, which will return a line number in the list of indexes and then add 1 to that to the the line in the dgIndexes of the next index.
