Non-contiguous selections don't work

[austin1howard]

If a non-contiguous selection (that is, not one big rectangular block) is passed to mpxl, error occurs.

This works

from appscript import app

areas = app("Microsoft Excel").selection.areas.get()
selection = areas.pop(0).value.get()
for area in areas:
    selection = [row + area.value.get()[rowIndex] for rowIndex,row in enumerate(selection)]
print selection
