Where:
- imol1 is an integer number
- imol2 is an integer number
- chain_imol1 is a string
- chain_imol2 is a string
- chain_used_flag_imol1 is an integer number
- chain_used_flag_imol2 is an integer number
- move_imol2_copy_flag is an integer number
chain-based interface to superposition.
Superpose the given chains of imol2 onto imol1. imol1 is reference, we can either move imol2 or copy it to generate a new molecule depending on the vaule of move_imol2_flag (1 for move 0 for copy).
