Imports corrected
Changed emit_log.go to handle multiple command line args
Changed receive_logs.go to declare the Exchange so that if it is run
before emit_log it will not panic.
Added check to verify that sufficient args are supplied.
Corrected the range to skip Args[0] (which is the command itself)
Corrected execute statements to have topic arguments
Corrected argument handling
Merge pull request #46 from mandolyte/master
