Counts the dimensions of an array. If $all is set to false (which is the default) it will
only consider the dimension of the first element in the array.

| $array | array | Array to count dimensions on |
| $all | boolean | Set to true to count the dimension considering all elements in array |
| $count | integer | Start the dimension count at this number |
