# FUNCTION : CHECK BASE CLASS
#
# Parameters:
# r4 : Base class to check (p_baseClass)
#
# Returns:
# r2 = -1 : If the base class is not unique (Base class > 0x80);
# Unit index : If a unit with the specified base class is found without crystal or treasure status;
# -2 : If the base class refers to a unit that doesn't exist / is disabled (Unit flags at 0x183 = 0x00);
# -3 : If a unit with the specified base class (r4) was found with status crystal or treasure, or was disabled;
# -4 : If no unit was found with the specified base class in battle, but was in the party;
# -5 : Otherwise
#
# int check_base_class (int p_baseClass)
