=head2 invoke({ class => class_name, function => function_name, params => function_params})

To avoid require, eval and invocation from within a block of code, which is suboptimal, 
the proxy object instantiates the object, invokes the function with the given params hash and returns the result.

  my ($self,$params) = @_;

    or throw RWDE::DevelException({  info => 'Proxy::Parameter error - function not specified'});

  my $term = RWDE::AbstractFactory->instantiate($params);

  return $term->$function($params);
