"""
A FlexGridSizer is basically the same as a GridSizer, except not all
cells are the same size.  A cell is as wide as the widest item in that
column and as high as the tallest item in that row.  Additionally,
rows and columns are not stretchable by default, but you can specify
which rows and columns should stretch when there is additional space
available.
