Remove dependency on json structure

[LifeofMichal]

Currently, the app is build for the to work with the single json data endpoint -> https://api.imgflip.com/get_memes

People may want to sometimes compare other things than memes, like phones, computers, financial plans, even people. The purpose of this ticket is to create a filter feature which will enable the app to recognize a structure of any JSON data it receives.

Followingly, the app will create and fill it's fields based on the data from the endpoint.
