#### Description

MR to add another xavp_copy function taking 4 params

``` xavc_copy("source_name", "source_index", "destination_name", "destination_index") ```

This will let the user copy to a specific position in the stack (replacing its value). This would bring coherent behaviour compared to assign to a specific index vs appending.

Example : swapping xavp in and existing stack: (second and third elements) ``` $xavp(a=>x) = "a-0-x"; $xavp(a[0]=>y) = "a-0-y"; $xavp(a=>x) = "a-1-x"; $xavp(a[0]=>y) = "a-1-y"; $xavp(a=>x) = "a-2-x"; $xavp(a[0]=>y) = "a-2-y";

# INFO: <script>: NEW $xavp(a[0]) = [a-2-x][a-2-y] # INFO: <script>: NEW $xavp(a[1]) = [a-1-x][a-1-y] # INFO: <script>: NEW $xavp(a[2]) = [a-0-x][a-0-y]

xavp_copy("a", "1", "c"); xavp_copy("a", "2", "a", "1"); xavp_copy("c", "0", "a", "2");

# INFO: <script>: AFTER $xavp(a[0]) = [a-2-x][a-2-y] # INFO: <script>: AFTER $xavp(a[1]) = [a-0-x][a-0-y] # INFO: <script>: AFTER $xavp(a[2]) = [a-1-x][a-1-y] ``` You can view, comment on, or merge this pull request online at:
