+/**
+ * A utility class to help log timings splits throughout a method call.
+ * Typical usage is:
+ * <p/>
+ * <pre>
+ *     TimingLogger timings = new TimingLogger(TAG, "methodA");
+ *     // ... do some work A ...
+ *     timings.addSplit("work A");
+ *     // ... do some work B ...
+ *     timings.addSplit("work B");
+ *     // ... do some work C ...
+ *     timings.addSplit("work C");
+ *     timings.dumpToLog();
+ * </pre>
+ * <p/>
+ * <p>The dumpToLog call would add the following to the log:</p>
+ * <p/>
+ * <pre>
+ *     D/TAG     ( 3459): methodA: begin
+ *     D/TAG     ( 3459): methodA:      9 ms, work A
+ *     D/TAG     ( 3459): methodA:      1 ms, work B
+ *     D/TAG     ( 3459): methodA:      6 ms, work C
+ *     D/TAG     ( 3459): methodA: end, 16 ms
