This module allows to use python formaulas to compute the sale order line price.

You can configure the 'Price formula' on the product form using python code.

Formula example: ``` area = float(properties['Width']) * float(properties['Length']) result = area / 2.0 if 'Painting' in properties:

result = result + 5

```

When changing properties on sale order line, the system will automatically compute the line price unit.
