crm_core_match.module in CRM Core 8

Manages matching engines for identifying duplicate contacts in CRM Core.

Allows CRM Core to install, enable and disable matching engines.

A matching engine is used to do the following:

• identify duplicate contact records
• inject data into contact records being saved
• carry out other scripted operations not easily handled in the normal

bootstrapping process.

This module does not define any matching engines itself, it only provides the framework through which they can be applied to new contacts being created in the database.

@TODO: add hooks for altering the submission process
