> We need to do some work on yarn top's shell code.
> a) Just checking for TERM isn't good enough.  We really need to check the return on tput,
especially since the output will not be a number but an error string which will likely blow
up the java code in horrible ways.
> b) All the single bracket tests should be double brackets to force the bash built-in.
> c) I'd think I'd rather see the shell portion in a function since it's rather large.
 This will allow for args, etc, to get local'ized and clean up the case statement.
