Not all classes are being printed in allFunctions

[samasri]

In order to print the output in allFunctions, classes in each hierarchy are traversed, and functions in each class are outputted. This method skips all the classes that have no parents or children and hence are not recorded in hierarchies
Solution:

• Add each class with no parent to an empty hierarchy so that it can be processed with the hierarchies.
• Add isSingle field to Hierarchy
• When printing hierarchies, filter them so that single hierarchies are not printed
