% showImage - displays an image in a convenient way.
%
% showImage(img) - displays image in a new window
%    img can be of any numerical type or a logical, and it
%        must have two (gray-scale) or three (RGB) dimensions.
%    img can be an Image structure (see initializeImage).
%    The image is scaled appropriately.
%
% showImage(img,title)
%    Rename the figure window to title.
%
% showImage(img,...,doNormalize)
%    If doNormalize is 1, the image is maximum-normalized 
%    (default: 0).
%
% h = showImage(...)
%    returns the handle of the figure.
%
% See also displayImage, displayMap, displayMaps, initializeImage, dataStructures.
