       This module (while experimental) encapsulates the exporting of keywords and routines. It applies the
       Validation::Class framework along with any keyword routines and/or sub-routines specified with the
       apply_spec() method. It does this by simply by copying the spec into the calling class.

       To simplify writing exporter modules, "Validation::Class::Exporter" also imports "strict" and "warnings"
       into your exporter module, as well as into modules that use it.

apply_spec
       When you call this method, "Validation::Class::Exporter" builds a custom "import" method on the calling
       class. The "import" method will export the functions you specify, and can also automatically export
       "Validation::Class" making the calling class a Validation::Class derived class.

       This method accepts the following parameters:

       •       routines => [ ... ]

               This  list  of  function  namesonly  will be exported into the calling class exactly as is, the
               functions can be used traditionally  or  as  keywords  so  their  parameter  handling  should  be
               configured accordingly.

       •       settings => [ ... ]

               This   list   of   key/value   pair   will   be   passed   to   the  load  method  imported  from
               "Validation::Class::load" and will be applied on the calling class.

               This approach affords you some trickery in that you can utilize the  load  method  to  apply  the
               current class' configuration to the calling class' configuration, etc.

               my $class = shift || caller;

               # routine as a keyword

               # ... do some thing

           };

       ... in your application class:

           package MyApp;

           use MyApp::Validator;

           thing ['a', 'b'];

       ... in your application:

           package main;

           my $app = MyApp->new;
