Html5EditorFor is an extension of default MVC 3 EditorFor, which allows to:

• Use custom attributes in View: Html.Html5EditorFor(model => model, null, attributes: new { style = "font-weight: bold" })
• Generate [HTML 5 Input type] (http://www.w3schools.com/html5/html5_form_input_types.asp) based on:
• type of the property (int, float, double etc.)
• DataType attribute form System.ComponentModel.DataAnnotations
• using custom Html5*Attribute from library over ViewModel

Additionally, it extends default input classes to include 'numeric-int' for not decimal numbers and 'numeric-float' for decimal numbers. This allows to use jQuery plugin like numeric i.e.: $('.numeric-int').numeric()
