class Task(object):
*******************


def __init__(self, ns, elem, validator, cp, path, chain_level, depth,
memory_models, models=None, bgroup=None, bg_part_ind=0):
====================================================

Initialize Task object

ns -- xml namespace as str
elem -- xml element as ElementTree object
validator -- validator (Lexicon) instance
cp -- ConditionParser instance
path -- task path in model_chain hierarchy
chain_level -- task evaluation level as str
depth -- depth of model chain hierarchy as int
memory_models -- memory_model names as a set of strings
models -- model instances
bgroup -- branching group name as str
bg_part_ind -- branching group part indice as int


def _construct_chain_task(self, ns, elem):
==========================================

Constructs a nested task-subtasks structure


def _get_model_impl(self, mtype, model=None, all=False):
========================================================

Checks that the implementation really exists for the task's model.
Optionally returns all implementations of the given type

mtype -- model type
model -- model name
all -- boolean for returning all implementations


def _set_model_and_param(self, ns, elem):
=========================================

Extract the model parameter definitions from an XML element if the model exists
Stores the model object and creates the model parameter object instance according to the model type
