Constrain geometry editting so invalid geometries cannot be created.
--------------------------------------------------------------------

         Key: UDIG-665
         URL: http://jira.codehaus.org/browse/UDIG-665
     Project: uDIG
        Type: New Feature

  Components: tool edit  
    Versions: UDIG 1.2    
    Reporter: Jesse Eichar
 Assigned to: Jesse Eichar 


Tools should check that the geometry is valid.  There are two ways to do this.

1. On an attempted accept action (double click, switch tool, etc...)  the geometry can be validated if it is not valid editing can be rolled back until it is valid or a message can be delivered to user indicating that the geometry is invalid and must be fixed.

2. Each edit  can do a validate.  This could be prohibitive depending on size of geometries.
