instance, group by 'Type' (Odoo Core, OCA, other...)

This module can be usefull in the following cases :

* To analyse the size of your technical debt, regarding your Custom modules
* To know the ratio between Odoo / OCA and Custom modules
* To evaluate the amount to pay to odoo to upgrade your custom code, or the
  induced workload
