Ability to block connections #11
Description
The algorithm will connect any nodes which it sees a connection. Sometimes this may not be desired, such as when drawing to adjacent and parallel fences. Therefore, the user should be able to paint a "blocking" layer, or similar, to act as an invisible barrier
Another implementation of this would be to have 5 types of posts:
- universal post, connects all 4 dir.
- 3 way, connects 3 dir. rotate based on desired connection
- 2 way
- e.t.c.
The second impl. is easier, but would be cumbersome and confusing. I will attempt to implement the first solution idea.
