-BitBake 'Data' implementations
-
-Functions for interacting with the data structure used by the
-BitBake build tools.
-
-The expandData and update_data are the most expensive
-operations. At night the cookie monster came by and
-suggested 'give me cookies on setting the variables and
-things will work out'. Taking this suggestion into account
-applying the skills from the not yet passed 'Entwurf und
-Analyse von Algorithmen' lecture and the cookie 
-monster seems to be right. We will track setVar more carefully
-to have faster update_data and expandKeys operations.
-
-This is a treade-off between speed and memory again but
-the speed is more critical here.
