* Once you have compiled or downloaded gson-2.8.1.jar, assuming you have placed it in the
17+
* same folder as this file (BingImageSearch.java), you can compile and run this program with the following steps:
18+
* 1. create three directories, named "bin", "src", and "lib"
19+
* 2. place this .java file in "src"
20+
* 3. download the latest gson .jar file online, and place it in the "lib" folder
21+
* 4. replace the subscriptionKey value with your valid Cognitive services subscription key
22+
* 5. run the following commands, replacing "lib/gson-2.8.5.jar" with your .jar file:
23+
* javac -d bin -sourcepath src -cp lib/gson-2.8.5.jar src/BingImageSearchv7Quickstart.java
24+
