> There is a lot of code duplication when it comes to decomposing commands into keyspace,
column family, keys, columns, etc, and validating the results. There would be even more if
the error handling was more thorough.
> I think the cleanest way is to create a class that accepts a CommonTree in its constructor
and assigns the results to members. A custom exception can be thrown for validation errors
and CliClient can simply trap these, print the descriptive .msg, and return.
