+/**
+ * Threaded class to check for updates in the background.
+ * <P>
+ * This is the class that handles the mind control and stuff for
+ * spying on our users and stealing their personal information.
+ * A random ID number is generated for each user, and hits the server
+ * to check for updates. Also included is the operating system and
+ * its version and the version of Java being used to run Processing.
+ * <P>
+ * The ID number also helps provide us a general idea of how many
+ * people are using Processing, which helps us when writing grant
+ * proposals and that kind of thing so that we can keep Processing free.
