/***************************************************************************
 * IpplStats keeps statistics about a given IPPL job, and can report on
 * a summary of these statistics when asked.
 *
 * To add a new type of statistic, do these steps:
 *   1. Add a new private variable to accumulate the stats
 *   2. Add a new public method to call to add values to the stat
 *   3. In the constructor, initialize the stats object with a name in the
 *      colon-initializer list.
 *   4. Add commands to the rest of ippl to change the stat as needed.
 *      Example:
 *                 #ifndef IPPL_NO_STATS
 *                 Ippl::Stats.incMessageSent();
 *                 #endif
 *
 * This interface is extensible ... you can add new types of statistics
 * by calling 'addStat(description, initval)' with a string description
 * of the stat, and the initial value it should have.  This will return a
 * unique integer identifier for that stat.  Then, you can modify the stat
 * by calling incStat(statindex, amount) and decStat(statindex, amount).
 * At the end, then, this statistic will be printed out just like all the
 * others.
