Number field draft v0.1.0

Lets people enter a number, by typing it or stepping it up and down.

A number field collects a numeric value within optional bounds and steps: a quantity, a percentage, a year. It is a Text field for numbers, with the platform's own stepping control (arrow keys, a spin control) and validation of the bounds. A value whose exact figure matters less than its position in a range is a Slider; a phone number or a postal code is text, not a number: use a Text field.
