//This is work in progress. Apply SOLID and DRY because it is too long and complex
//Future modifications:
//1. Done (Send the buttons as modiffiers, so they can be attached only when needed)
//2. Done (Image modifier to wrap a specific column, just as NationalFlag one)
//3. Done (String formatter to separate camel-case in different words)
//4. Icons on buttons
//5. Exception handling here and in the related classes
