1) remove some unnecessary and commented code in module
hra_math.time_domain.poincare_plot.poincare_plot_generator

2) changes in the class
hra_math.model.parameters.poincare_plot_parameters.PoincarePlotParameters:
a) change model to store information about parameter's info, instead of
a member 
self.__parameters_info__
use
self.__parameters_groups__ of dictionary type to put all parameters
infos 
grouped by type of parameter: common, statistics, movie;
all the code which used self.__parameters_info__ had to be changed to
reflect
grouping of parameters infos, especially methods:
def __getattr__(self, name)
def addParameterInfo(self, group, name, default, _help,
group_description)
def parameters_info_count(self)
def get_infos_lines(self, valued_only=False) [new method]

put code creating lines of parameter's info into method
def get_infos_lines(self, valued_only=False)
the old method info(self, valued_only=False) uses the method
get_infos_lines
to get the lines and print them on the screen

b) remove method: def parameters_info(self)
c) remove in a inner class
class __ParameterInfo__(object)
members: movie_parameter, statistics_parameter 
because use of new member PoincarePlotParameters.__parameters_groups__

3) use in method
hra_math.time_domain.poincare_plot.poincare_plot.PoincarePlotManager.__save_members__
method PoincarePlotParameters.get_infos_lines to get lines which have to
be saved into poincare plot parameters file
