created base model class inside newly created models folder

This is the class where all models should extend so as to access the database
Merge branch 'master' of https://github.com/antsago/WeetyNews
Added active record orm folder to project
Made the base model use active record instead of PDO
Added Models to project
Added services to project
Deleted database file as its no longer needed

Base model used to extend from this class but since it used PDO( which we are no longer using), we no longer need it
