Purpose
=======
Make it possible to compare analytic values between plans by inputting
up to one account per plan on each line.
For instance, if we have 2 plans: "Country" and "Product Type", with the
following accounts
| Country | Product Type |
| ------- | ------------ |
| BE | Drinks |
| LU | Food |
And the following invoices:
* 1000€ of drinks in Belgium
* 2000€ of food in Belgium
* 3000€ of food in Luxemburg
We want to be able to display the following pivot tables:
| | Drinks | Food | Total |
| --- | ------ | ---- | ----- |
| BE | 1000 | 2000 | 3000 |
| LU | 0 | 3000 | 3000 |
| Tot | 1000 | 5000 | 6000 |
| | Total |
| ------ | ----- |
| Food | 5000 |
| * BE | 2000 |
| * LU | 3000 |
| Drinks | 1000 |
| * BE | 1000 |
| Total | 6000 |
Implementation
==============
* `ir.fields` are added/removed dynamically on `account.analytic.line`
* Each analytic plan corresponds to one field on `account.analytic.line`
* The fields are added dynamically in the views.
* `account.analytic.plan` doesn't have a `company_id` field anymore,
meaning that all the companies have access to all the plans. This
means that the applicability fields and lines are now company
dependent, and those can be used to know which fields/plans to display
for which company.
* There can no longer be one "Project" plan per company, even if the
accounts of that project can still be owned by only one company.
* There is now only one method to get the default (or "Project" plan),
which is `_get_plan_columns`
