a) add a new function:
hra_core.introspection.get_normal_instance_members(obj, excludes=[])
which returns all usual instance fields (not properties or methods)

b) combine all poincare plot parameters into one class 
hra_math.model.parameters.poincare_plot_parameters.PoincarePlotParameters
remove parameters classes included in modules:
data_vector_parameters
file_data_parameters
filter_parameters
movie_parameters
statistic_parameters

all poincare plot properties as normal instance members (excluding for
example property methods) are managed in class:
PoincarePlotParameters
by 2 instance methods:
    def setter(self, name, value)
    def getter(self, name)

c) introduce required changes in GUI classes which used above  deleted
(point b)) poincare parameters classes
