# Build An Initial Symbol Table #
#---------------------------------------------------------------------------#
# One of the options of this test driver is to initialize a test
# symbol table. To make it easy to change the contents of this test
# symbol table, we use the following scheme:
# The data below is used to populate an initial symbol table. The
# init code takes care of actually reading this table and populating
# the symbol table for you. So, you just have to maintain this table
# properly and the program will do all the actual initialization work
# for you.
# Each symbol has an entry in the form of a Python list with the
# following items/order:
#
# Name, Value, Writeable, Type, Default, LegalVals, Min, Max
#
# **** NOTE: Where 'None' appears, the init code just uses the
# ***default*** established by the VarDescriptor base class.

# Deriving Your Own Types

# and then derive a new object type for your own convenience. This is
# a way to set your own defaults, for example.
# Note the use of 'super()' here to run each constructor in the
# inheritance tree only once.
