Order a 2-D stack of image based on pair-wise similarity (computed as a cross-correlation coefficent).

1. Use option initial to specify which image will be used as an initial seed to form the chain.

2. If options initial is omitted, the program will determine which image best serves as initial seed to form the chain
sp_chains.py input_stack.hdf output_stack.hdf --radius=25
3. Use option circular to form a circular chain.
