Title: Error Catch Lastz

The change alerts the user if lastz is not correctly installed or is broken on his or her computer. Previously, the code ran an operation checking the status of lztstderr, but didn't alert the user if an issue arose. Now, an else statement raises an exception which alerts the user if lastz is not working.
