Refactor PR #74 to avoid dependency on the PPI module.
Pull request #74 had a dependency on the PPI module which made its inclusion into master not so attractive for users not using the feature. By refactoring the part of the code that depended on PPI out in a separate module, only the users that would like to use the feature needs to install the extra dependencies.
The code that still remains in master (that is the code that does not depend on PPI) now implements a plugin hook in the write_label() sub in Data::Printer::Object. An option in the configuration file called caller_plugin is used to register a caller plugin. If such a plugin is registered, write_label() will load the plugin and use the plugin to do the generation of the label string.
The refactored part of #74 that depends on PPI has been included in a module Data::Printer::Plugin::Caller::PPI (currently only on Github).
