Created third weekly task, a form build.
Merge branch 'master' of github.com:mirai-wordpress/yeswecan
Add HTML5 form.

It manages 4 types of data:

    - text
    - number (with range)
    - email
    - textarea

Interesting: 'required' attribute is used for validating the field. Too, the
'type' attribute. HTML5 makes everything smoothly for us.
