HIPS example code using the "Checkout API"

This code is provided by HIPS as a simple example of invoking order create and get actions.

Note that this code uses an HTTParty option debug_output (set to $stdout). This option should not be used in production code, as it calls the NET::HTTP method set_debug_output.

See note here.
