MAIN EXAMPLE:
rest-server-example.c : A RESTful server example showing how to use the REST layer to develop server-side applications (possible to run it over either COAP or HTTP)
To use COAP as the underlying application protocol, one should define WITH_COAP = 1 in rest-example/Makefile. Otherwise, HTTP is used.
Look at the source code to see which resources are available. (check the RESOURCE macros in the code).
Look at the source code to see which resources are available. (check the RESOURCE macros in the code).
Each resource has a handler function which is called by the REST layer to serve the request.
(i.e. "helloworld" resource has a handler function named "helloworld_handler" which is called when a web service request is received for "helloworld" resource.)

Accessing the server from outside:

After loading the cooja file, open another another terminal pointing to the same directory and connect to the COOJA simulation using tunslip6:

Now you need to use a COAP or HTTP client to interact with the COOJA nodes running REST code.
In this setting, two servers are available:
IP addresses are aaaa::0212:7402:0002:0202 and aaaa::0212:7403:0003:0303. COAP uses 61616, whereas HTTP uses 8080 port.

You can use curl as an http client to interact with the COOJA motes running REST code.
