# This Module provides named scope for:
#
# - Search records in a extjs way (but can reusable)
# - Paginate records in a extjs way (but can be reusable)
# - Add association to the model (used for search in dependents tables)
#
# Examples:
#
# invoices = current_account.store.invoices.with(:order).ext_search(params)
# invoices_count = invoices.size
# invoices_paginated = invoices.ext_paginate(params)
#
