You can configure some common name patterns for the inverse function
in Settings > General settings:

* Lastname Firstname: For example 'Anderson Robert'
* Lastname, Firstname: For example 'Anderson, Robert'
* Firstname Lastname: For example 'Robert Anderson'

After applying the changes, you can recalculate all partners name clicking
"Recalculate names" button. Note: This process could take so much time depending
how many partners there are in database.

You can use *_get_inverse_name* method to get lastname and firstname from a simple string
and also *_get_computed_name* to get a name form the lastname and firstname.
These methods can be overridden to change the format specified above.
