Measure the size of each product in an edm::event Provides the output as an ascii table or root histograms
Based on the original implementation by Luca Lista
Algorithm: Measure the size of each branch in a tree as the sum of the sizes of all its baskets Estimate the "size in memory" multipling the actual branch size by its compression factor
