Fixes #84

While Filtering data , schools will also shown in map in different color than center when we apply both (school/center) filter .

Using school list like in your first commit is a better idea as school-center-distance has a much larger row count.

Also instead of re-reading from tsv can we use dataframe in tab3? and build a dict[scode , (lat,long)] from from it so that we dont have to traverse school list multiple times
