Minimal setup to use Apache's HTTPClient in a Processing sketch.

import org.apache.http.impl.client.DefaultHttpClient;

// http://hc.apache.org/httpcomponents-client-ga/tutorial/html/fundamentals.html - Apache HttpClient
// https://forum.processing.org/topic/http-post-processing - Integration with Processing (different from above)
// https://code.google.com/p/processing/source/browse/trunk/processing/java/libraries/net/examples/HTTPClient/HTTPClient.pde?r=7950 - Messy.
// https://github.com/francisli/processing-http - Unnecessary?
// This code assumes the presence of the following Apache HTTPClient JARs added to the sketch's 'code' directory:
// - httpclient-4.2.3.jar
// - httpcore-4.2.2.jar
// - commons-logging-1.1.1.jar
// This can be accomplished by manually copying, or by using 'Add File' in the Processing IDE.
// It does _not_ work to add these JARs to the sketchbook/libraries directory for some unknown reason.
