function iterAbs( iterator ) {
	return iterMap( iterator, abs );
}
Returns an iterator which iteratively computes the absolute value.

## Notes

-   If an environment supports `Symbol.iterator` **and** a provided iterator is iterable, the returned iterator is iterable.

@param {Iterator} iterator - input iterator
@throws {TypeError} must provide an iterator protocol-compliant object
@returns {Iterator} iterator

@example
var randu = require( '@stdlib/random/iter/randu' );

var iter = iterAbs( randu() );

var r = iter.next().value;
// returns <number>

r = iter.next().value;
// returns <number>

r = iter.next().value;
// returns <number>

// ...
