key term list should be dynamic

[Ali Hürriyetoglu]

currently the key terms that can be selected are just a static list. Enable the automatic calculation, get the most frequent n.

I pushed the codes in my branch views.py. I got the keywords from the database with pymongo. I used mongodb query(distinct) to get keywords from the database.

pymongo_local_client=pymongo.MongoClient() # connecting local mongodb client on ugur's computer.
pymongo_local_db=pymongo_local_client.myugurdb # connecting local mongodb database on ugur's computer.
pymongo_local_keywordlist=pymongo_local_db.floodtags20140729.distinct( "keywords") # getting the keywords descending order from floodtags20140729 collection.
print(pymongo_local_keywordlist) # you can see the keywords on terminal after running codes.
keywordlist = pymongo_local_keywordlist[:11] # getting the top 10 keywords from the dataset.
