Write a method that takes an ArrayList of Strings, and an int numRepeats and returns a new ArrayList with the original ArrayList repeated numRepeats times.

For example if we had an ArrayList list with the values $[$a$,$b$,$c$]$:

repeatArrayList$($list$,3)$

Should return a new ArrayList with the elements:

$["$a$","$b$","$c$","$a$","$b$","$c$","$a$","$b$","$c$"]$
