 value.  It currently does not use these data directly from
 the EPW input, relying instead on a dew-point-to-W calculation.
 This follows the request and recommendations of David G-M.

+Removed limitation in rfluxmtx, which was disallowing distant
+and local receivers. Found this to be a perfectly valid approach
+for some annual daylighting scenarios.
+
+Wrote new pvsum tool to handle cases dctimestep can't, like
+spectral input pictures.  It also adds a -N option for multi-
+processing on Unix machines, which utilizes memory-mapped
+inputs for efficient i/o sharing.
+
+Made it so genBSDF can use spectral rendering for a
+more accurate photometric result.
