    Ejemplo #1 Ds\Vector::insert() example

    <?php
    $vector     = new \Ds\Vector();

    $vector->insert(0, "e"); // [e]
    $vector->insert(1, "f"); // [e, f]
    $vector->insert(2, "g"); // [e, f, g]
    $vector->insert(0, "a", "b"); // [a, b, e, f, g]

    object(Ds\Vector)#1 (7) { [0]=> string(1) "a" [1]=> string(1) "b" [2]=> string(1) "c" [3]=> string(1) "d" [4]=> string(1) "e" [5]=> string(1) "f" [6]=> string(1) "g" }
