/**
* A checkbox matrix
* Operates similarly to HTMLMultiSelectField, but instead of using an array of
* options, uses an array of rows and an array of columns to dynamically
* construct a matrix of options. The tags used to identify a particular cell
* are of the form "columnName-rowName"
*
* Options:
* - columns
* - Required associative array mapping column labels (as HTML) to their tags.
* - rows
* - Required associative array mapping row labels (as HTML) to their tags.
* - force-options-on
* - Array of column-row tags to be displayed as enabled but unavailable to change.
* - force-options-off
* - Array of column-row tags to be displayed as disabled but unavailable to change.
* - tooltips
* - Optional associative array mapping row labels to tooltips (as text, will be escaped).
* - tooltips-html
* - Optional associative array mapping row labels to tooltips (as HTML).
* Only used by OOUI form fields. Takes precedence when supported, so to support both
* OOUI and non-OOUI forms, you can set both.
* - tooltip-class
* - Optional CSS class used on tooltip container span. Defaults to mw-icon-question.
* Not used by OOUI form fields.
*
* @stable to extend
