Code refactoring #5

[pakoromilas]

Code refactoring is probably done.

Things done:

1. Made code PEP8 compliant
2. Created 11 functions :
   • display_histogram
   • initialize_face
   • remove_overlaps
   • seconds_to_time
   • color_analysis
   • update_faces
   • shot_change
   • calc_shot_duration
   • windows_display
   • get_features_stats
   • display_time
3. Removed 2 functions:
   • drawArrow : replaced with cv2.arrowedLine command
   • anglesCluster : it was not used
4. Modified some parts of the rest of the code to make it more efficient
5. Wrote docstrings for every function and for the module itself.

Things to consider: A banch of functions are not used or work properly at the time.

• [x] get_hsv_histograms_2d function is not used. Keep or remove?

• [x] dirs_process_video function suppose to run dir_process_video for different directories, but is not used. Add this functionality to the code?

• [x] analyze and script_debug functions don't work. Keep them for future modification or remove?

• [x] npy_to_csv not used for the time

@tyiannak , @theopsall and @apoman38 please take a look at the code and tell me if everything looks and works fine. For any question you can ask me in the comments, or read the docstrings provided to the functions.

Let's keep dirs_process_video and npy_to_csv (even though they are not used) and remove the rest (get_hsv_histograms_2d, analyze / script debug)
