the current vision

must return an s-expression

the type of vision

must be a single word, no spaces allowed

is used to distinguish between sources and to build up an s-expression with multiple vision types

could be described in short as the "LISP name"

i.e. "lines", "flowangle"

Implements ActCvSource.
