# Model Configuration Dictionary:
#
# Define the model parameters and adjust for any modifications if imported
# from a sub-experiment.
#
# These fields might be modified by a sub-experiment; this dict is passed
# between the sub-experiment and base experiment
#
#
# NOTE: Use of DEFERRED VALUE-GETTERs: dictionary fields and list elements
#   within the config dictionary may be assigned futures derived from the
#   ValueGetterBase class, such as DeferredDictLookup.
#   This facility is particularly handy for enabling substitution of values in
#   the config dictionary from other values in the config dictionary, which is
#   needed by permutation.py-based experiments. These values will be resolved
#   during the call to applyValueGettersToContainer(),
#   which we call after the base experiment's config dictionary is updated from
#   the sub-experiment. See ValueGetterBase and
#   DeferredDictLookup for more details about value-getters.
#
#   For each custom encoder parameter to be exposed to the sub-experiment/
#   permutation overrides, define a variable in this section, using key names
#   beginning with a single underscore character to avoid collisions with
#   pre-defined keys (e.g., _dsEncoderFieldName2_N).
#
#   Example:
#      config = dict(
#        _dsEncoderFieldName2_N = 70,
#        _dsEncoderFieldName2_W = 5,
#        dsEncoderSchema = [
#          base=dict(
#            fieldname='Name2', type='ScalarEncoder',

#            n=DeferredDictLookup('_dsEncoderFieldName2_N'),
