v2.2.0

• Fix for changing edge colors #7
• jinja2 latest version is supported again #9
• added Two scaler for node size and edge width (zscore and minmax). The minmax was the default but frequently resulted in skewed values, and thus sizes and width because of outliers. The zscore is more robust against outliers and now the default.
• edge_color can now also be based on clustering colors: d3.set_node_properties(edge_color='cluster')
• The minimum and maximum range of the node size can be set with the parameter (minmax): d3.set_node_properties(minmax=[10, 50])
• The minimum and maximum range of the edge width can be set with the parameter (minmax): d3.set_edge_properties(minmax=[1, 10])
• Documentation pages updated
