=head1 NAME

Workflow::Base - Base class with constructor

=head1 VERSION

This documentation describes version 1.60 of this package

=head1 SYNOPSIS

 package My::App::Foo;
 use base qw( Workflow::Base );

=head1 DESCRIPTION

Provide a constructor and some other useful methods for subclasses.

=head1 METHODS

=head2 Class Methods

=head3 new( @params )

Just create a new object (blessed hashref) and pass along C<@params>
to the C<init()> method, which subclasses can override to initialize
themselves.

Returns: new object

=head2 Object Methods

=head3 init( @params )

Subclasses may implement to do initialization. The C<@params> are
whatever is passed into C<new()>. Nothing need be returned.

=head3 log()

Returns the logger for the instance, based on the instance class.

=head3 param( [ $name, $value ] )

Associate arbitrary parameters with this object.

If neither C<$name> nor C<$value> given, return a hashref of all
parameters set in object:

 my $params = $object->param();
 while ( my ( $name, $value ) = each %{ $params } ) {
     print "$name = $params->{ $name }\n";
 }

If C<$name> given and it is a hash reference, assign all the values of
the reference to the object parameters. This is the way to assign
multiple parameters at once. Note that these will overwrite any
existing parameter values. Return a hashref of all parameters set in
object.

 $object->param({ foo => 'bar',
                  baz => 'blarney' });

If C<$name> given and it is not a hash reference, return the value
associated with it, C<undef> if C<$name> was not previously set.

 my $value = $object->param( 'foo' );
 print "Value of 'foo' is '$value'\n";

If C<$name> and C<$value> given, associate C<$name> with C<$value>,
overwriting any existing value, and return the new value.

 $object->param( foo => 'blurney' );

=head3 delete_param( [ $name ] )

Delete parameters from this object.

If C<$name> given and it is an array reference, then delete all
parameters from this object. All deleted parameters will be returned
as a hash reference together with their values.

 my $deleted = $object->delete_param(['foo','baz']);
 foreach my $key (keys %{$deleted})
 {
   print $key."::=".$deleted->{$key}."\n";
 }

If C<$name> given and it is not an array reference, delete the
parameter and return the value of the parameter.

 my $value = $object->delete_param( 'foo' );
 print "Value of 'foo' was '$value'\n";

If C<$name> is not defined or C<$name> does not exists the
undef is returned.

=head3 clear_params()

Clears out all parameters associated with this object.

=head3 normalize_array( \@array | $item )

If given C<\@array> return it dereferenced; if given C<$item>, return
it in a list. If given neither return an empty list.
