added possiblity to access cell data
added code to wrap imglib1 cellcontainer into imglib2 cellimg
fixed bug that linkedtype was not set
fixed bug that the containerfactory provided to wrap it is actually the right one.
otherwise making a clone of a wrapped cellimg would fail.
finished wrappers for imglib1 > imglib2
finished wrappers imglib1 <-> imglib2 for array and cell
