 """Defines class Rietveld to easily access a rietveld instance.
 
 Security implications:
 
 The following hypothesis are made:
 - Rietveld enforces:
   - Nobody else than issue owner can upload a patch set
   - Verifies the issue owner credentials when creating new issues
   - A issue owner can't change once the issue is created
   - A patch set cannot be modified
