Lire::Config::Scalar - Lire Config container for scalar values
=head1 SYNOPSIS
use Lire::Config::Scalar
=head1 DESCRIPTION
This package contains the class to represent a scalar in an actual
configuration.
=head1 Lire::Config::Scalar
Value container for scalar values. Implements simple methods to get()
and set() string data.

=head2 get()
Returns this scalar's value.
=cut
sub get {

}
=pod
=head2 set( $val )
This method can be used to change this scalar's value.
=cut

$self->{'value'} = $val;
}
=pod
=head2 is_valid()
Checks with the parameter's spec that the current value is valid.
