-----------------------------------------------------------
The problem was in the documentation of the scan command, not the actual
command itself. Scan must take in the name of the table, and may optionally
take an array of columns *or* an array of columns and scanner specifications.
Scan will not accept only a table name and scanner specifications. The
attached patch makes this more clear in the documentation, and gives the user a
warning if they use scan with only a table name and scanner specifications.
The tests in bin/HBase.rb and bin/Formatter.rb all passed.
