Extend K2 with many field types and powerful search

The main goal of Sherpa is to replace the standard K2 extrafields. When i say replace, i don't say hack or modify. It's just another place to manage extrafields for K2.
With Sherpa, you'll be able to :

• Create field groups (same process as standard)
• Create field and assign it to a group (same process as standard)
• Assign one or more groups to a category, an item or a user
• Create searches with different fields and different filters to retrieve categories, items or users with great ordering features
• Display search modules related to created searches with specific templates
• Link items, users, categories to other items, users or categories via a specific 'link' field
• Add new extrafield types via plugins

Of course, as usual, all that without K2 hacks.
