Detailed Description

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

An empty filter accepts everything. 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)
*
