% displayPyramid - displays a pyramid in a new figure.
%
% displayPyramid(pyr)
%    Displays all levels of pyr in a new figure.
%
% displayPyramid(pyr,normalizeFlag)
%    If normalizeFlag is 1, the maps are maximum-normalized,
%    if it is 2, then the maps are max-normalized and scaled
%    to the dimensions of map.origImage (default: 0).
