gregexp: Regular expressions with submatches

This module extends the regexp module in OTP R7B-1 with support for submatches (the \(...\) syntax in SED regular expressions). This makes it possible to retrieve several components of a match with a single evaluation of a regexp. For example:

    Eshell V5.0.1.1  (abort with ^G)
    1> RE_URL="\\(.+\\)://\\(.+\\)\\(/.+\\)(\\?\\(.*\\)(&\\(.*\\))*)?".
    "\\(.+\\)://\\(.+\\)\\(/.+\\)(\\?\\(.*\\)(&\\(.*\\))*)?"
  
    2> gregexp:groups("http://localhost:81/script?arg", RE_URL).
    {match,["http","localhost:81","/script","arg"]}
  
    3> gregexp:groups("http://localhost:81/script?arg&arg2&arg3", RE_URL).
    {match,["http","localhost:81","/script","arg","arg2","arg3"]}

pool_server: A generic load-balancer for Erlang gen_servers.

A process which masquerades as a gen_server and forwards requests to a pool of workers (gen_servers). gen_fsms with a synchronous API are supported too.
