-========================================================================
-    CasaLens Project Overview
-========================================================================
-
-CasaLens is a data mash-up sample i.e use the Casablanca features to build a service that can collate data from different services and provide them to the user. 
-Given the postal code/city name, the service overlays events, movies, weather, pictures around the place.
-
-To run the sample, obtain the api keys from the different services (listed below) and update them in casalens.cpp (see Services section below for more details).
-The sample takes one parameter: the port to listen for requests.
-
-Services:
-Here are the details about the services the sample is interacting with, how to obtain the api keys for using these services and how to pass it to the sample. 
-1. Bing image search: http://datamarket.azure.com/dataset/bing/search
-   Sign UP at the above link to obtain the api key.
-   In casalens.cpp, set the value of bmaps_key variable to this key.
-   Query this service for pictures of a place and return it to the client.
-   This service is also used to collect movie posters.
-
-2. OpenWeatherMap:http://openweathermap.org/ 
-   Fetch weather data: current temperature, pressure at the location.
-
-3. Eventful: http://http://api.eventful.com/
-   Follow the "Get Started" steps -> "Register a new account" at the eventful website to obtain the application key.
-   In casalens.cpp, set the value of events_key variable to this key.
-   Fetch different events happening at the specified location.
-
-4. OnConnect tmsapi: http://developer.tmsapi.com/
-   Register at the above website and obtain a new key for the TMS API package.
-   In casalens.cpp, set the value of movies_key variable to this key.
-   Get currently playing movies in local theaters along with the show times.
-   
-5. Google maps: https://developers.google.com/maps
-   This does not require a key.
-   Given a postal code, use google maps API to get the location (city name) corresponding to that code.
-
-6. Bing maps: http://dev.virtualearth.net/
-   The key populated in step 1 should work for both bing maps and search.
-   Given a location (city name), use bing maps API to get the postal code.
-
-Files:
-1. casalens.cpp: 
-   Main file that contains code to initialize and start the http_listener.
-   We add two GET and POST handlers handle_get and handle_post and open the listener to listen for requests.
-
-2. datafetcher.cpp:
-   This file contains logic to collect data from different services, create JSON objects with the data and return it to the client.
-
-This sample is merely a demonstration of how one can use Casablanca to author data mash-ups. 
-If you plan to use/deploy the sample, do not forget to read and follow the "Terms and Conditions" for each service and ensure that you are adhering to all the requirements.
