Overview

A wrapper is an object that holds several components and render them. A component may either be a symbol or any object that responds to ‘render`. This API allows inputs/components to be easily wrapped, removing the need to modify the code only to wrap input in an extra tag.

‘Many` represents a wrapper around several components at the same time. It may optionally receive a namespace, allowing it to be configured on demand on input generation. The find function returns if it matches namespace
