[IMP] mrp_hook: Provide hooks for _bom_explode method
As we are struggled by the structure of core current code, and https://github.com/odoo/odoo/pull/8885 hasn't been accepted in v8, we need to make this hard move to allow a lot of workarounds like modules not depending this one, but anyway the method itself is not too much inheritable.

===============================
|
||||
Hooks for enabling advanced MRP
|
||||
===============================
|
||||
|
||||
Technical module that provides the proper framework infrastructure (hooks,
|
||||
fallback, etc) to enable advanced functionality in the manufacturing area,
|
||||
as https://github.com/odoo/odoo/pull/8885 hasn't been accepted for v8.
|
||||
|
||||
* Hooks in *_bom_explode* method for returning dictionary for consume and
|
||||
workcenter lines.
|
||||
* Provide product and template.
|
||||
|
||||
By itself it doesn't provide anything, but serves as base for others modules
|
||||
to develop its features.
|
||||
|
||||
Known issues / Roadmap
|
||||
======================
|
||||
|
||||
* This module fully overwrites _bom_explode method, so any other module
|
||||
inheriting this method should take that into account.
|
||||
* On v9, this module can be removed.

||||
