	* Tests if an array-like value contains a search value.
	*
	* ## Notes
	*
	* -   When `value` is a string, the function checks whether the characters of the search string are found in the input string. The search is case-sensitive.
	* -   When `value` is an array-like object, the function checks whether the input array contains an element which is the same as the specified search value.
	* -   For strings, this function is modeled after `String.prototype.includes`, part of the ECMAScript 6 specification. This function is different from a call to `String.prototype.includes.call` insofar as type-checking is performed for all arguments.
	* -   The function does distinguish between positive and negative zero.
	* -   If `position < 0`, the search is performed for the entire input array or string.
	*
	* @param value - input value
	* @param searchValue - search value
	* @param position - position at which to start searching for `searchValue` (default: 0)
	* @throws second argument must be a primitive string primitive when the first argument is a string
	* @returns boolean indicating whether one value contains another

	*
	*     -   `d`: days
	*     -   `h`: hours
	*     -   `m`: minutes
	*     -   `s`: seconds
	*     -   `ms`: milliseconds
	*
	*     For example, the string `1m3s10ms` is a duration string containing three time units: `1m` (1 minute), `3s` (3 seconds), and `10ms` (10 milliseconds). The string `60m` is a duration string containing a single time unit: `60m` (60 minutes). Time units must be supplied in descending order of magnitude (i.e., days, hours, minutes, seconds, milliseconds).
	*
	* -   Duration strings are case insensitive. For example, the string `1M3S10MS` is equivalent to `1m3s10ms`.
	*
	* @param value - value to test
