		* The checks attribute is an array of check objects
		* Each check object can contain the following attributes
		* `id` - string(required). This uniquely identifies the check. If the check already exists, this will result in any supplied check properties being overridden. The properties below that are marked required if new are optional when the check is being overridden.
		* `evaluate` - function(required for new). This is the function that implements the check's functionality.
		* `after` - function(optional). This is the function that gets called for checks that operate on a page-level basis, to process the results from the iframes.
		* `options` - mixed(optional). This is the options structure that is passed to the evaluate function and is intended to be used to configure checks. It is the most common property that is intended to be overridden for existing checks.
		* `enabled` - boolean(optional, default `true`). This is used to indicate whether the check is on or off by default. Checks that are off are not evaluated, even when included in a rule. Overriding this is a common way to disable a particular check across multiple rules.
		* `rules` - Used to add rules to the existing set of rules, or to override the properties of existing rules
		* The rules attribute is an Array of rule objects
		* each rule object can contain the following attributes
		* `id` - string(required). This uniquely identifies the rule. If the rule already exists, it will be overridden with any of the attributes supplied. The attributes below that are marked required, are only required for new rules.

		* `excludeHidden` - boolean(optional, default `true`). This indicates whether elements that are hidden from all users are to be passed into the rule for evaluation.
		* `enabled` - boolean(optional, default `true`). Whether the rule is turned on. This is a common attribute for overriding.
		* `pageLevel` - boolean(optional, default `false`). When set to true, this rule is only applied when the entire page is tested. Results from nodes on different frames are combined into a single result. See [page level rules](#page-level-rules).
		* `any` - array(optional, default `[]`). This is the list of checks that must all "pass" or else there is a violation.
		* `all` - array(optional, default `[]`). This is the list of checks that, if any "fails", will generate a violation.
		* `none` - array(optional, default `[]`). This is a list of the checks that, if none "pass", will generate a violation.
		* `tags` - array(optional, default `[]`). A list if the tags that "classify" the rule. In practice, you must supply some valid tags or the default evaluation will not invoke the rule. The convention is to include the standard (WCAG 2 and/or section 508), the WCAG 2 level, Section 508 paragraph, and the WCAG 2 success criteria. Tags are constructed by converting all letters to lower case, removing spaces and periods and concatinating the result. E.g. WCAG 2 A success criteria 1.1.1 would become ["wcag2a", "wcag111"]
