Bool OPDModulo2PI

If set, all OPD data will be computed as the fractional part of the total OPD. All OPD computations will return results that are between -π and +π, or -0.5 and +0.5 waves. This method of computing OPD may have applications to some specific problems. However, its use is discouraged unless the user fully understands the meaning and ramifications of computing OPD in this manner.
