Description

make_region is introduced in #77 to make a region of sites that will be updated in an alternating update/sweeping algorithm. This issue is to track potential improvements, for example:

  1. Generalize it to n-site updates.
  2. Think about how we might improve the design of how the reverse step of TDVP is incorporated.
