Add All Data To SQLite Database

[thealphadollar]

It is important to add all the disasters' data to one database file and provide
access on API endpoint basis to it.

Requires the creation of a Database collection which will provide the following
functions:

• add bunch of data to (to be done manually by the developer).
• return the list of dict of disasters for a country (for now) from the queried
  country.
• delete duplicate data.

#TODO: think of more functions
