2016-10-27 Change size for folium maps

There is no option to change the size of a folium map embedded in a notebook. I updated function folium_html_map to do so.

import folium
map_osm = folium.Map(location=[48.85, 2.34])
from pyensae.notebook_helper import folium_html_map
map_osm.polygon_marker(location=[48.824338, 2.302641], popup='ENSAE', fill_color='#132b5e', num_sides=3, radius=10)
folium_html_map(map_osm, width="50%")
