<commit_before># The Global robustness module implements a simplified (and faster) variant of the global
# robustness measure outlined in <NAME>'s Master's Thesis.
#
# Methods executed under global robustness protection are executed within an exception
# catching block which intercept any errors which cause the method to fail 
#
# For now this measure only works with simple methods that do not change the state of 
# objects or interfere with the global state.
#
# NEED TO CLONE PARAMETERS.
