Sorted dict 1

Pull request for SortedDict and BalancedTree23 taking into account Kevin Squire's feedback from the past 12 days.
Dear Kevin,

I figured out the answers to my own questions in my previous post... 
first, I got the latest Julia nightly today using apt-get update and 
upgrade.  Apparently it was delayed by one day compared to Windows.

Second, I figured out that I am getting the SIGKILL in my Julia code 
because there isn't enough swap space, as I have determined by using the 
'watch' command in linux.  Apparently I set up my virtual linux machine 
with incorrect memory sizes.  So next I will figure out how to increase 
the swap space for Ubuntu running inside VirtualBox, hopefully without a 
complete reinstall, and then I'll go back to working on code coverage.
