/*
 * General RcontribSimulManager class operation:
 *
 *  1)  Call LoadOctree(), then alter the header as desired
 *  2)  Set number of spectral samples (NCSAMP) and call SetDataFormat()
 *  3)  Call AddModifier() and AddModFile() to indicate tracked modifiers
 *  4)  Set outOp and cdsF according to desired output/recovery
 *  5)  Call PrepOutput() to open output channels
 *  6)  Call SetThreadCount() to fork children if desired
 *  7)  Set accum to the number of ray samples per record
 *  8)  Call ComputeRecord() with accum ray samples
 *  9)  Continue until GetRowMax() records have been sent
 * 10)  Call Cleanup()
 *
 * The order of some of these calls may be changed.  Technically, the octree
 * may be loaded anytime before PrepOutput() is called.  Also, SetThreadCount()
 * may be called anytime after PrepOutput() and interleaved with
 * calls to ComputeRecord().  The accum setting may be changed at any time.
 * Finally, it is possible to restart the output using ResetRow(), and
 * a zero argument will rewind to the beginning, whence all records
 * may be recalculated.  The previous output rows are not zeroed or deleted,
 * but are overwritten as the calculation proceeds from the new starting point.
 * However, the output file(s) will indicate in the NROWS= line in the header
 * that only the newly calculated rows are present.
 *
 * It is not possible to write to standard output, but the output
 * model is quite flexible thanks to the RdataShare polymorphic class.
 * The current default output class creates a shared, memory-mapped file,
 * which is the most efficient object on most systems.
 *
 * ASCII output is not supported, so full data recovery is.

124	* General RcontribSimulManager class operation:
125	*
126	* 1) Call LoadOctree(), then alter the header as desired
127	* 2) Set number of spectral samples (NCSAMP) and call SetDataFormat()
128	* 3) Call AddModifier() and AddModFile() to indicate tracked modifiers
129	* 4) Set outOp and cdsF according to desired output/recovery
130	* 5) Call PrepOutput() to open output channels
131	* 6) Call SetThreadCount() to fork children if desired
132	* 7) Set accum to the number of ray samples per record
133	* 8) Call ComputeRecord() with accum ray samples
134	* 9) Continue until GetRowMax() records have been sent
135	* 10) Call Cleanup()
136	*
137	* The order of some of these calls may be changed. Technically, the octree
138	* may be loaded anytime before PrepOutput() is called. Also, SetThreadCount()
139	* may be called anytime after PrepOutput() and interleaved with
140	* calls to ComputeRecord(). The accum setting may be changed at any time.
141	* Finally, it is possible to restart the output using ResetRow(), and
142	* a zero argument will rewind to the beginning, whence all records
143	* may be recalculated. The previous output rows are not zeroed or deleted,
144	* but are overwritten as the calculation proceeds from the new starting point.
145	* However, the output file(s) will indicate in the NROWS= line in the header
146	* that only the newly calculated rows are present.
147	*
148	* It is not possible to write to standard output, but the output
149	* model is quite flexible thanks to the RdataShare polymorphic class.
150	* The current default output class creates a shared, memory-mapped file,
151	* which is the most efficient object on most systems.
152	*
153	* ASCII output is not supported, so full data recovery is.
