Methods summary
`public static array`	# `range( mixed $low, mixed $high, Closure $step, Closure $compare = null )` Creates an array containing item range. Similar to range() but with closures. Params $low and $high are inclusive. If $low > $high, resulting array will be in descending order. Creates an array containing item range. Similar to range() but with closures. Params $low and $high are inclusive. If $low > $high, resulting array will be in descending order. Parameters `$low` `mixed` Minimal value `$high` `mixed` Maximal value `$step` `Closure` Closure which creates next value from current `$compare` `Closure` comparing closure for detecting if we're at the end of the range (Optional) Returns `array`
`public static array`	# `keymap( Traversable $traversable, Closure $key, Closure $value = null )` Creates an associative array from iterator which doesn't return proper keys. Keys are generated by applying callback $key to the current value. It is also possible to apply another callback directly to the value. Key callback is called BEFORE value callback.

Example: $data = \Jyxo\Spl\ArrayUtil::keymap($iterator, function(Object $object) { return $object->getId(); }); Parameters `$traversable` `Traversable` Iterator `$key` `Closure` Closure for generating keys `$value` `Closure` Closure for modifying data (Optional) Returns `array`
