drscheme:rep:current-rep in DrScheme Tools Functions

• (drscheme:rep:current-rep) -> (or/c false/c (is-a?/c drscheme:rep:text%))

  This is a parameter whose value should not be set by tools. It is initialized to the repl that controls this evaluation in the user's thread.

  It only returns #f if the program not running in the context of a repl (eg, the test suite window).
