MaterialNumberValueAccessor class

ControlValueAccessor which will coerce an input into a num.

Use materialNumberInputDirectives to get a set of directives to use with the input to provide validations. Such as the default to ensure it is a number, checkInteger, checkPositive, checkNonNegative (allows 0,) lowerBound, and upperBound.

keypressUpdate attribute has the value update on every keypress while the default is the value only updating on a blur event. blurFormat attribute causes the input to be formatted on blur events.
