the creation of the table airports. It is not necessary
to run because hibernate does it but I upload it anyway
 as a repository
id column had no constraints, now it does
all the airports i was able to find (that have a IATA code).

This repository must be run in order to have data in the
 auto-complete feature
raw data of airports taken from... i'm not quite sure
final version od back end. If got more time, i'll include
custom exception creations and maybe a more clear name fo the project
