Introducing a float type?

[jpetitcolas]

We often have to customize the number type to be able to deal with float numbers, using something similar to:

nga.field('float_attribute', 'number').attributes({ step: 'any' }).format('0.000');

What about offering a float type out of the box, including the previous configuration?

Great idea, and quite easy to achieve.
