| * Collects performance data between two function calls in Bundle objects and |

| * <p> |
| * {@link #beginSnapshot(String)} and {@link #endSnapshot()} functions collect |
| * memory usage information and measure runtime between calls to begin and end. |
| * These functions logically wrap around an entire test, and should be called |
| * with name of test as the label, e.g. EmailPerformanceTest. |
| * <p> |
| * {@link #startTiming(String)} and {@link #stopTiming(String)} functions |
| * measure runtime between calls to start and stop. These functions logically |
| * wrap around a single test case or a small block of code, and should be called |
| * with the name of test case as the label, e.g. testSimpleSendMailSequence. |
| * <p> |
| * {@link #addIteration(String)} inserts intermediate measurement point which |
| * can be labeled with a String, e.g. Launch email app, compose, send, etc. |
| * <p> |
| * Snapshot and timing functions do not interfere with each other, and thus can |
| * be called in any order. The intended structure is to wrap begin/endSnapshot |
| * around calls to start/stopTiming, for example: |

| * startTiming("testSimpleSendSequence"); |
| * addIteration("Launch email app"); |

| * stopTiming("Send"); |
| * startTiming("testComplexSendSequence"); |
| * stopTiming(""); |

| * endSnapshot();</code> |
