/**
+ * TestCollection is a reimplementation of the Multihop Oscilloscope application
+ * using TOSThreads. It periodically samples a universal software-based SineSensor
+ * and broadcasts a message every few readings. These readings can be displayed by
+ * the Java "Oscilloscope" application found in the the TestCollection/java
+ * subdirectory. The sampling rate starts at 4Hz, but can be changed from the Java
+ * application.
+ *
+ * At least two motes must be used by this application, with one of them installed
+ * as a base station. Base station motes can be created by installing them with
+ * NODE_ID % 500 == 0.
+ * i.e. make <platform> cthreads install.0
+ * make <platform> cthreads install.500
+ * make <platform> cthreads install.1000
+ *
+ * All other nodes can be installed with arbitrary NODE_IDs.
+ * make <platform> cthreads install.123
+ *
+ * Successful running of this application is verified by all NON-base station motes
+ * periodically flashing LED1 upon sending a message, and the base station mote,
+ * flashing LED2 upon successful reception of a message. Additionally, correct
+ * operation should be verified by running the java tool described in the following
+ * section.
