## @brief Generate a random editorial model

#
# The random generator can be tuned with integer parameters
# that represent probability or maximum numbers of items.
# The probability (chances) works like 1/x chances to append
# with x the tunable parameter
# Tunable generator parameters :
# - classtype : Chances for a classtype to be empty (default 0)
# - nclass : Maximum number of classes per classtypes (default 5)
# - nofg : Chances for a classe to have no fieldgroup associated to it (default 10)
# - notype : Chances for a classe to have no type associated to it (default 5)
# - seltype : Chances for a type to select an optionnal field (default 2)
# - ntypesuperiors : Chances for a type to link with a superiors (default 3)
# - nofields : Chances for a fieldgroup to be empty (default 10)
# - nfields : Maximum number of field per fieldgroups (default 8)
# - rfields : Maximum number of relation_to_type attributes fields (default 5)
# - optfield : Chances for a field to be optionnal (default 2)
# @param backend : A backend to use with the new EM
# @param **chances dict : Provide tunable generation parameter
