# Object extension to allow numbered LP variables to be initialised dynamically using the following
# syntax.
#
# [Capitalized_varname][lp var type suffix]
#
# Where lp var type suffix is either _b for binary, _i for integer, or _f for float.
# I.e
#
# Rating_i is the equivalent of Rating (type integer)
# Is_happy_b is the equivalent of Is_happy (type binary/boolean)
