2738	/*
2739	JSHINT is a global function. It takes two parameters.
2740
2741	var myResult = JSHINT(source, option);
2742
2743	The first parameter is either a string or an array of strings. If it is a
2744	string, it will be split on '\n' or '\r'. If it is an array of strings, it
2745	is assumed that each string represents one line. The source can be a
2746	JavaScript text or a JSON text.
2747
2748	The second parameter is an optional object of options which control the
2749	operation of JSHINT. Most of the options are booleans: They are all
2750	optional and have a default value of false. One of the options, predef,
2751	can be an array of names, which will be used to declare global variables,
2752	or an object whose keys are used as global names, with a boolean value
2753	that determines if they are assignable.
2754
2755	If it checks out, JSHINT returns true. Otherwise, it returns false.
2756
2757	If false, you can inspect JSHINT.errors to find out the problems.
2758	JSHINT.errors is an array of objects containing these members:
2759
2760	{
2761	line : The line (relative to 0) at which the lint was found
2762	character : The character (relative to 0) at which the lint was found
2763	reason : The problem
2764	evidence : The text line in which the problem occurred
2765	raw : The raw message before the details were inserted
2766	a : The first detail
2767	b : The second detail
2768	c : The third detail
2769	d : The fourth detail
2770	}
2771
2772	If a fatal error was found, a null will be the last element of the
2773	JSHINT.errors array.
2774
2775	You can request a Function Report, which shows all of the functions
2776	and the parameters and vars that they use. This can be used to find
2777	implied global variables and other problems. The report is in HTML and
2778	can be inserted in an HTML <body>.
2779
2780	var myReport = JSHINT.report(limited);
2781
2782	If limited is true, then the report will be limited to only errors.
2783
2784	You can request a data structure which contains JSHint's results.
2785
2786	var myData = JSHINT.data();
2787
2788	It returns a structure with this form:
2789
2790	{
