  "A <i>class</i> defines a grouping of variables (properties) and functions (methods) that are common to a certain type \
   of thing, for instance dogs, cars, balls, people, etcetera. A class is a blueprint for such things.<br />\
   Each <i>object</i> of a class gets its own copy of all the properties defined in the class.\
   For example, every object (instance) of a car class would have its own brand, color, type, speed, position, engine volume, etcetera.<br />\
   Methods are simply functions that an object can call. They are meant to relate to that specific object of a class.\
   For example, objects of a car class could have methods such as 'accelerate()' or 'brake()'.\
   Objects are often used to model real-world things in programming, e.g. balls.",
