Variable expansion for demands

[networmix]

Consider:

NetGraph DSL-inspired

  entry:
    source_path: "region{r}/.*/rbb_plane{p}/rb"
    sink_path: "region{r2}/rbb_plane{p}/rb"
  expand_vars:
    p: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16]
    r: ["region1"]
    r2: ["region2"]
  expansion_mode: "cartesian"

With bracket expansion (NetGraph parser.py style)

  entry:
    source_path: "region1/.*/rbb_plane[1-16]/rb"  # Expanded at parse time
