Class 'test': data cache for simulations

Description

test is an S4 class for representing data cache for running simulations. Despite the name, this class does not represent a test and is not related to a test. That is, test length is not stored in this class. This class is only kept for backwards compatibility. The functionality of this class is superseded by simulation_data_cache.
