Some notes on adding collection-specific plugins and macros.

Plugins go into collect/colname/perllib/plugins

Macros go into collect/colname/macros

• It's best to put modified plugins into collect/colname/perllib/plugins , so any other collections can still use the standard ones.
• A collection specific plugin has to have the same name as an existing plugin if you are over-riding the system-wide version of the plugin.
• The collection-specific one is used instead the system-wide one.
• The 'collection specific' plugin appears in the gli when you have that collection loaded.

Collection specific macro files go into collect/colname/macros, and are used instead of the system ones.
