Selected star #101

Closed rapodaca closed 2 years ago

rapodaca commented 2 years ago

As it stands, there is no way to select the star (*) atom explicitly because it can not be made lower case. This means that strings such as "*1ccccc1" will be invalid because the corresponding DS has no perfect matching.

Options:

  1. State exactly that.
  2. Add rules for indirect selection of star atom.
  3. Invent a symbol for selected star.
