This PR adds a new helper trait called the ValidatorTrait to validate variables in ways that I find myself having to write manually over and over and over again. It will throw a special InvalidVariableException class to be thrown if the validation is unsuccessful.
Please check that it is fully unit tested.
It has the following public methods:
checkNumeric() - Checks that a value of any scalar type is numeric
checkWholeNumber() - Checks that a value of any scalar type is a whole number
checkScalar() - Checks that a value is scalar, i.e. can be cast to a string. In this instance, null counts as scalar, even though the is_scalar() function does not allow for it
checkInstance() - Checks that a value is an instance of a class or interface
