Internet Shield Example

This example shows an application on 1Sheeld's internet shield.

By using this example, you can get response of certain GET request and 
print it all out on the terminal shield 64 bytes by 64 bytes.
 
OPTIONAL:
To reduce the library compiled size and limit its memory usage, you
can specify which shields you want to include in your sketch by
defining CUSTOM_SETTINGS and the shields respective INCLUDE_ define.
