/** \brief Fundamental class template for arrays of equal-sized images.
An ImageArray manages an array of images of the type given as
template parameter. Use it like a ArrayVector<ImageType>, it has
the same interface, only operator< is missing from ImageArray. It
offers additional functions for resizing the images and querying
their common size. See \ref imageSize() for additional notes.
A custimized allocator can be passed as a template argument and via the constructor.
By default, the allocator of the <tt>ImageType</tt> is reused.
