A decorator to define functions to extend the context used in a template rendering.
report_name must be the xml id of the desired report (it is mandatory to indicate the
module in that xml id).
The given function will be called at the creation of the report. The following arguments
will be passed to it (in this order):
- pool The model pool.
- cr The cursor.
- uid The user id.
- localcontext The context given to the template engine to render the templates for the
current report. This is the context that should be modified.
