/*
This class wraps around display elements like headers and paragraphs, and
creates inputs / textareas to edit them with.
The placeholder text for the edit elements comes from the
data-editor-placeholder attribute of the display elements if available.
The on_open, on_save and on_cancel callbacks will receive two arguments:
1. This editor object.
2. the edit elements as either:
If the display elements ALL have data-editor-id attributes,
then a dictionary of {data-editor-id: edit_element, ...}.
Otherwise, an array of [edit_element, ...] in their original order.
When your callbacks are used, the default `open`, `save`, `cancel`
methods are not called automatically. You should call them from within
your function.
