[ADD] contract_variable_quantity:

=================================================
Variable quantity in contract recurrent invoicing
=================================================

With this module, you will be able to define in recurring contracts some
lines with variable quantity according a provided formula.

Configuration
=============

* Go to Sales > Configuration > Contracts > Formulas (quantity).
* Define any formula based on Python code that stores at some moment a
  float/integer value of the quantity to invoice in the variable 'result'.

  You can use these variables to compute your formula:

  * *env*: Environment variable for getting other models.
  * *context*: Current context dictionary.
  * *user*: Current user.
  * *line*: Contract recurring invoice line that triggers this formula.
  * *contract*: Contract whose line belongs to.
  * *invoice*: Invoice (header) being created.

Usage
=====

To use this module, you need to:

* Go to Sales -> Contracts and select or create a new contract.
* Check *Generate recurring invoices automatically*.
* Add a new recurring invoicing line.
* Select "Variable quantity" in column "Qty. type".
* Select one of the possible formulas to use (previously created).

<h3>Help with Python expressions.</h3>
<p>You have to insert valid Python code block that stores at some moment a float/integer value of the quantity to invoice in the variable 'result'.</p>
<p>You can use these variables to compute your formula:</p>
<ul>
<li><i>env</i>: Environment variable for getting other models.</li>
<li><i>context</i>: Current context dictionary.</li>
<li><i>user</i>: Current user.</li>
<li><i>line</i>: Contract recurring invoice line that triggers this formula.</li>
<li><i>contract</i>: Contract whose line belongs to.</li>
<li><i>invoice</i>: Invoice (header) being created.</li>
</ul>
