* Interpolate values into a string template.
*
* Syntax:
*
* math.print(template, values)
* math.print(template, values, precision)
* math.print(template, values, options)
*
* Example usage:
*
* // the following outputs: 'Lucy is 5 years old'
* math.print('Lucy is $age years old', {age: 5})
*
* // the following outputs: 'The value of pi is 3.141592654'
* math.print('The value of pi is $pi', {pi: math.pi}, 10)
*
* // the following outputs: 'hello Mary! The date is 2013-03-23'
* math.print('Hello $user.name! The date is $date', {
* user: {
* name: 'Mary',
* },
* date: new Date(2013, 2, 23).toISOString().substring(0, 10)
* })
*
* // the following outputs: 'My favorite fruits are apples and bananas !'
* math.print('My favorite fruits are $0 and $1 !', [
* 'apples',
* 'bananas'
* ])
*
* See also:
*
* format
*
* @param {string} template A string containing variable placeholders.
* @param {Object | Array | Matrix} values An object or array containing variables
* which will be filled in in the template.
* @param {number | Object} [options] Formatting options,
* or the number of digits to format numbers.
* See function math.format for a description
* of all options.
* @return {string} Interpolated string
