/// Client that runs data through a StanfordCoreNLPServer either just for testing or for command-line text processing.
/// This runs the pipeline you specify on the
/// text in the file(s) that you specify (with -file or -filelist) and sends some results to stdout.
/// The current code in this main method assumes that each line of the file
/// is to be processed separately as a single sentence.
/// A site must be specified with a protocol like "https:" in front of it.
/// Example usage:<br />
/// java -mx6g edu.stanford.nlp.pipeline.StanfordCoreNLP -props properties -backends site1:port1,site2:port2 <br />
/// or just -host https://foo.bar.com [-port 9000]
