|
;; commentary
|
|
;; aims to provide a simple framework for testing VPL models, ideas
|
|
;; or techniques. this code is based around the implicit assumption
|
|
;; that a VPL will be a graph based representation which is mapable
|
|
;; to a sexp (or collection of sexps), so some things should be
|
|
;; reasonably common between different (although admittedly graph
|
|
;; based) VPLs, for example graph traversal, node placement and layout.
|
|
;; it is not intended to be complete, exhaustive, or stable.
