<p>Converts the given array into a {@link Map}. Each element of the array
must be either a {@link Map.Entry} or an Array, containing at least two
elements, where the first element is used as key and the second as
value.</p>

<pre>
// Create a Map mapping colors.

<p>This method returns {@code null} for a {@code null} input array.</p>

@param array  an array whose elements are either a {@link Map.Entry} or
 an Array containing at least two elements, may be {@code null}
@return a {@code Map} that was created from the array
@throws IllegalArgumentException  if one element of this Array is
 itself an Array containing less then two elements
@throws IllegalArgumentException  if the array contains elements other
 than {@link Map.Entry} and an Array
