 It works by identifying segments of the two proteins with similar local
 structure, and then combining those to try to align the most residues possible
 while keeping the overall RMSD of the superposition low.

 It performs similarly to CE for most proteins. The 'rigid' flavor uses a
 rigid-body superposition and only considers alignments with matching sequence
 order.
