Describes the `coor` field of a need-debug-input nrepl response from cider-nrepl middleware

cider-nrepl-coor-description.txt

COORDINATES is a list of integers that specify how to navigate into the
sexp that is after point when this function is called.
As an example, a COORDINATES list of '(1 0 2) means:
  - enter next sexp then `forward-sexp' once,
  - enter next sexp,
  - enter next sexp then `forward-sexp' twice.
In the following snippet, this takes us to the (* x 2) sexp (point is left
at the end of the given sexp).
    (letfn [(twice [x]
              (* x 2))]
      (twice 15))
In addition to numbers, a coordinate can be a string.  This string names the
key of a map, and it means \"go to the value associated with this key\
