Bug fixes for the analyse singleton which prevented us from caching.
Caching now works but it is discouraged to try this with analysing
HUSACCT. (After an hour of caching I decided to turn it off.)
DependencyDTO now contains a 'via' field, this to see via which class
the indirect dependency is called.
Via is currently only supported in the 'Analysed Application Overview'
menu till it is proven that this is really he right way to display the
dependencies.
