as a portal type information.

The Coordinate class now provides methods that allow to do all the
"presentation" specific part of a Coordinate in a set of python scripts.

For example, to add a CreditCard portal type information :
- go to portal_types, choose 'Add ERP5 Type Information', select 'ERP5
  Coordinate' and name your new type 'Credit Card'
- go to your newly created 'Credit Card' type definition, and add 'CreditCard'
  to its list of Property Sheets.
- create a new form for your CreditCard : CreditCard_view and add a field
  named my_text to it.
- create two scripts, which will interact with the 'my_text' field :
  - CreditCard_fromText(text) : used to analyse the text entered by the user,
    and fill in the object's properties accordingly.
  - CreditCard_asText() : used to return a user-readable aggregation of the
    object's properties.

These two python scripts can use regular expressions to analyse the text
entered by the user, using the object's methods getRegularExpressionFindAll
and getRegularExpressionGroups for example.
