Handing of Self-Referencial Links like TOC

[BlockSecCA]

While doing a graph walk it seems the TOC notation causes trouble as the result are notes that link to nothing.

There could be two outcomes:

• A note that refers to itself using `[[#...|]] notation may not result on a valid edge
• A note that refers to itself generates as many self referential edges as entry in the TOC.

There is also another consideration: a note can link to another note using the "[[#" syntax which is the same as used for TOC. Does that create an edge between the two notes?
