LibreOffice imports multicolumn texboxes as tables. When
document has numCols=2 (or more) attribute at slidelayout and slide,
the table rows and columns duplicates.
maPPTShapes vector holds our PPTShape objects, hasSameSubTypeIndex
function finds the status that I mention above. So that we can prevent
that duplication.
