Simple Bot to reply messages.
First, a few handler functions are defined. Then, those functions are passed to
the Dispatcher and registered at their respective places.
Then, the bot is started and runs until we press Ctrl-C on the command line.
Basic Echobot example, repeats messages.
Press Ctrl-C on the command line or send a signal to the process to stop the

# Define a few command handlers. These usually take the two arguments bot and
