Subject: Column-table: enkodiranje numerickih kolona i izlazne kolone
 disabled; ispravljen bag kad korisnik ne cekira nijednu kolonu ili cekira
 jednu za koriscenje (upozorenje). Napravljene input varijable za
 prosledjivanje potrebnih vrednosti pie-chart i boxplot komponentama od strane
 column-table. Profile page: dodata klasa za hover odabir profilne slike.
