Turtle and Observer Command

ask-list-of-turtles `[list of turtle ID numbers] [list of commands]`

Turtles whose `who` numbers (ID numbers) are in `[list of turtle ID numbers]` run `[list of commands]`. The caller of this command waits for it to finish before continuing. If some invalid `who` numbers make up `[list of turtle ID numbers]`, they are ignored.

Examples:
`ask-list-of-turtles [4 6 10 14] [fd 1]` makes 4 turtles (those with who numbers 4, 6, 10, and 14) move forward one step.
