1) changes in modules:
  hra_math.time_domain.poincare_plot.poincare_plot,
  hra_math.model.parameters.movie_parameters

- add new program parameter named:   movie_fast_generation
   if set to True then chaco library is applied to create a poincare
plot movie;
- change parameter name multi_proc_factor into
movie_multiprocessing_factor

2) changes in a module 
hra_math.time_domain.poincare_plot.poincare_plot_movie_maker
- add use of movie_fast_generation parameters, new function named
   def create_mini_poincare_plot_fast_generation(pp_specs_manager) is
applied

- some optimizations:
   members x_data, y_data of class PoincarePlotMovieMaker are allocated
once to the size of a signal;
   this imply during calculation of mini poincare plot parameters use
only put function to fill up these members,
   add a new member named s_size in class PoincarePlotMovieMaker to set
up actual size of processing mini poincare plot;
   comment garbage collection invocation in every turn of
add_data_vector_segment(...) method because of huge impact
   on processing time
   split self.pp_specs_managers array into sub arrays in method the def
__save_frames__(self)


3) changes in module 
hra_math.time_domain.poincare_plot.poincare_plot_fast_movie_worker
- add parameter first (with default False value) in function:
   def __update_graphics_context__(gc, scatter, pp_spec, first=False)
  used to check if this is the first mini poincare plot so all previous
active and inactive points
  have to be plotted
- comment use of previous_manager member of MiniPoincarePlotSpecManager
class, due to some difficulties
  during generating of a movie in context of multiprocessing approach
