=head1 NAME

CGI::Lazy::ErrorHandler

=head1 SYNOPSIS

	use CGI::Lazy;

	my $q = CGI::Lazy->new('/path/to/config/');

	eval {
		something();
	};

	if ($@) {
		$q->errorHandler->funkyErrorMethod;
	}

=head1 DESCRIPTION

CGI::Lazy::ErrorHandler is simply a bunch of canned error messages for displaying errors to the user.

At some point in the future, it will display them in a neater and more unified way, but for now, it's just a convenience object.
