Modified RecursiveJoin to have an printRecursiveArray option.  
This is needed since StringIO does not print out recursiveArray values  
while array.to\_s does.

For example:

a = [1,2,3]  
a \<\< a  
@io.puts(a) → prints "1\n2\n3\n[…]\n  
a.to\_s → prints “123123[…]”

Fixed all calls to Join to also pass in printRecursiveArray option.
