Project$$s description

This is a little fun project, and short, too. The project aims to define a class that allows the creation of new probability distributions based on existing ones. The solution needs to be a S$3$ class named randomVariate. The constructor of the class must accept two arguments. The first one, named distFormula, should be a formula, e$.$g$.,$ ~ x $+$ y$,$ describing the function of one or more random variables. The second argument, named defs, should be a list of functions used for sampling from given distributions with keys corresponding to symbols used in the formula. The created object of the class randomVariate should be a function used for sampling from the distribution defined by the formula. You should also write the print method specific to this class. The following examples should clarify the concept.
