/**
* Numbers a street address accordingly
*
* A street address contains a numeric street address in addition to, potentially,
* a numeric street name (e.g., "123 101st st"). The street name can be a number
* ("101"), an ordinal (e.g., "101st"), or a cardinal (e.g., "one hundred and
* first"). Ultimately, all of those should resolve to the same norm.
*
* For example:
*
* self::number("123 101 st"); // returns "123 101 st"
* self::number("123 101st st"); // returns "123 101 st"
* self::number("123 one hundred first st"); // returns "123 101 st"
* self::number("123 one hundred and first st"); // returns "123 101 st"
*
* @since 0.1.0
* @param string $street the street address to number
* @return string

* Returns true if $key does not exist in $array or $array[$key] is empty
*
* PHP's isset() method is will return false if the key does not exist or if the
* key exists and its value is null. However, it will return true if the key
* exists and its value is not null (including other "empty" values like '', false
* and array()).
*
* PHP's empty() method (or some frameworks) will throw a warning if you attempt
* to test a non-existant key in an array.
*
* I, on the other hand, will return false if the key does not exist in the array
* or if the key's value is empty.
*
* For example:
*
* $a = ['foo' => null, 'bar' => array(), 'qux' => 'hello'];
*
* // when key doesn't exist (!)
* isset($a['quux']); // returns false
* ! empty($a['quux']); // throws key-does-not-exist warning
* ! Arr::isEmpty('quux', $a); // returns false
*
* // when key does exist, but value is null
* isset($a['foo']); // returns false
* ! empty($a['foo']); // returns false
* ! Arr::isEmpty('foo', $a); // returns false
*
* // when key does exist, but value is "empty" (!)
* isset($a['bar']); // returns true
* ! empty($a['bar']); // returns false
* ! Arr::isEmpty('bar', $a); // returns false
*
* // when key does exist, but value is not "empty"
* isset($a['qux']); // returns true
* ! empty($a['qux']); // returns true
* ! Arr::isEmpty('qux', $a); // returns true
*
* @since 0.1.0
*
* @param string $key the key's name
* @param array $array the array to test
* @param bool $isZeroEmpty a flag indicating whether or not zero is
* considered empty (optional; if omitted, defaults to true - i.e., the
* default behavior of PHP's empty() function )
*
* @return bool true if the key exists and its value is not empty
*
* @throws \BadMethodCallException if $key or $array are null
* @throws \InvalidArgumentException if $key is not a string
* @throws \InvalidArgumentException if $array is not an array
