=head2 DESCRIPTION

Base class for each Playwright class magic'd up by Sub::Install in Playwright's BEGIN block.
You probably shouldn't use this.

The specification for each class can be inspected with the 'spec' property:

    use Data::Dumper;
    my $object = Playwright::Base->new(...);
    print Dumper($object->{spec});

=head1 CONSTRUCTOR

=head2 new(HASH) = (Playwright::Base)

Creates a new page and returns a handle to interact with it.

=head3 INPUT

    handle (Playwright) : Playwright object.
    id (STRING)         : _guid returned by a response from the Playwright server with the provided type.
    type (STRING)       : Type to actually use
