dCrawler pip package and animations

[Elsword016]

Added crawler_animate.ipynb in the Python_implementation folder and a gif of the same. I think the movie may not work as well as the MATLAB counterpart.
Added a pip ready package for dcrawler. We need a PyPI account to push to the public library.

If you want to test the package in /dCrawler. The directory has to follow a specific structure that's why I made a new folder, after we push the package in the public stream, we have to do a little cleanup maybe.

• Clone the repo.
• cd into the directory
• python setup.py sdist
• Then pip install .
  You can then import it into any file in the current environment.

from dCrawler import dCrawler
# Initialize the dCrawler object
crawler = dCrawler(threshold=1.0)
crawler.fit(data)
centroids,clusters = crawler.centroids,crawler.clusters
