Replace special characters "&", "<" and ">" to HTML-safe sequences.
If the optional flag quote is true (the default), the quotation mark
characters, both double quote (") and single quote (') characters are also
translated.
If a `HTMLString` is provied, it's assumed that whatever you give to
escape_html is a string with any unsafe values already escaped.

Generate HTML attribute syntax from inputted keyword arguments.
The output value is sorted by the passed keys, to provide consistent output
each time this function is called with the same parameters. Because of the
frequent use of the normally reserved keywords `class` and `for`, suffixing
these with an underscore will allow them to be used.
In order to facilitate the use of ``data-`` attributes, the first underscore
behind the ``data``-element is replaced with a hyphen.
>>> html_params(data_any_attribute='something')
'data-any_attribute="something"'
In addition, the values ``True`` and ``False`` are special:
* ``attr=True`` generates the HTML compact output of a boolean attribute,
e.g. ``checked=True`` will generate simply ``checked``
* ``attr=False`` will be ignored and generate no output.
>>> html_params(name='text1', id='f', class_='text')
'class="text" id="f" name="text1"'
>>> html_params(checked=True, readonly=False, name="text1", abc="hello")
'abc="hello" checked name="text1"'

HTMLStringa
This is an "HTML safe string" class that is returned by WTForms widgets.
For the most part, HTMLString acts like a normal unicode string, except
in that it has a `__html__` method. This method is invoked by a compatible
auto-escaping HTML framework to get the HTML-safe version of a string.
Usage::
HTMLString('')
c C s | S )a=
Give an HTML-safe string.
This method actually returns itself, because it's assumed that
whatever you give to HTMLString is a string with any unsafe values
already escaped. This lets auto-escaping template frameworks
know that this string is safe for HTML rendering.

Renders a list of fields as a `ul` or `ol` list.
This is used for fields which encapsulate many inner fields as subfields.
The widget will try to iterate the field to get access to the subfields and
call them to render them.
If `prefix_label` is set, the subfield's label is printed before the field,
otherwise afterwards. The latter is useful for iterating radios or
checkboxes.

Renders a list of fields as a set of table rows with th/td pairs.
If `with_table_tag` is True, then an enclosing
is placed around the
rows.
Hidden fields will not be displayed with a row, instead the field will be
pushed into a subsequent table row to ensure XHTML validity. Hidden fields
at the end of the field list will appear outside the table.

This is used as the basis for most of the other input fields.
By default, the `_value()` method will be called upon the associated field
to provide the ``value=`` HTML attribute.

Renders a select field.
If `multiple` is True, then the `size` property should be specified on
rendering to make the field useful.
The field must provide an `iter_choices()` method which the widget will
call on rendering; this method must yield tuples of
`(value, label, selected)`.
