Petal::Hash::Test - Test and Tutorial Petal modifier

       The modifier API is very, very simple. It consists of two elements:

   Thepackagename
       Your modifier should be called Petal::Hash::<SomeThing>, where <SomeThing> is the name that you want to
       give to your modifier.

       For example, this modifier is called Petal::Hash::Test. Petal will automatically pick it the module up
       and assign it the 'test:' prefix.

           package Petal::Hash::Test;
           use warnings;
           use strict;

   Themethod$class->process($hash,$argument);
       This class method will define the modifier in itself.

       * $class is the package name of your modifier (which might come in handy if you're subclassing a
       modifier),

       * $hash is the execution context, i.e. the objects and data which will 'fill' your template,

       * $argument is whatever was after your modifier's prefix. For example, for the expression 'test:foo bar',
       $argument would be 'foo bar'.

       In this test / tutorial we're going to write a modifier which uppercases a Petal expression.

         sub process
         {
             my $class    = shift;
             my $hash     = shift;
             my $argument = shift;

             return uc ($hash->get ($argument));
         }

         1;

         __END__

       And that's it! Simple!

       Petal modifiers are snippets of code which are used to extend the expression engine capabilities. This
       test shows how to write your own modifiers.
