# <mst> that requires 'build_per_context_instance'
# <mst> and provides an ACCEPT_CONTEXT that does the appropriate magic
# <mst> ACCEPT_CONTEXT would do the stash persist as well

=head1 NAME
Catalyst::Component::InstancePerContext -
Return a new instance a component on each request
=head1 SYNOPSYS
package MyComponent;
use Moose;
with 'Catalyst::Component::InstancePerContext';
sub build_per_context_instance{
my ($self, $c) = @_;
# ... do your thing here
return SomeModule->new(%args);
}
=head1 REQUIRED METHODS
Your consuming class B<must> implement the following method.
=head2 build_per_context_instance
The value returned by this call is what you will recieve when you call
$c->component('YourComponent').
=head1 PROVIDED METHODS
This role will add the following method to your consuming class.
=head2 ACCEPT_CONTEXT
If the context is not blessed, it will simple pass through the value of
C<build_per_context_instance>. If context is blessed it will look in the
C<stash> for an instance of the requested component and return that or,
if the value is not found, the value returned by C<build_per_context_instance>
will be stored and return.
The idea behind this behavior is that a component can be built on a
per-request basis, as the name of this module implies.
