1) change default values for size of points for active, inactive and
centroid parts of poincare plot to size of 4 in
hra_math.model.parameters.movie_parameters.MovieParameters class;
this change is correlated with use of chaco library which has different
specification of dimension of elements then matplotlib library used so
far as default library


2) changes in
hra_math.time_domain.poincare_plot.poincare_plot_movie_maker module:
move fields: active_color,  inactive_color, centroid_color,
movie_active_size, movie_inactive_size,
p.movie_centroid_size, show_plot_legends from class MiniPoincarePlotSpec
to MiniPoincarePlotSpecManager
because these entities correspond to the whole poincare plot;
the following modules are affected:
hra_math.time_domain.poincare_plot.poincare_plot_movie_worker
hra_math.time_domain.poincare_plot.poincare_plot_fast_movie_worker
