Detailed Description

Functor wrapper of allow/deny lists of wordRe for filtering.

An empty 'allow' accepts everything not in 'deny'. A literal 'allow' match has higher priority than any 'deny'. A regex 'allow' match has lower priority than any 'deny'.

Example (when applied to a list of words),

   input:  ( abc apple test other val val1 val2 wall wall1 wall2 )
   allow:  ( abc def "t.*" other val val1 "wall.*" )
   deny:   ( "[ab].*" "t.*" other "val[0-9]" wall )

   result:  (abc other val val1 wall1 wall2)
