class Enlighten::RadProbeSetMetaData
A data block that describes essential properties of a run-time probe set.
This data is effectively a header to any probe set data.
Among other things, the meta data contains the non-axis aligned bounding box that contains all probes in the probe set as well as information if the probes are structured as a regular grid. If it is structured as a regular grid then the position of each probe is implicitly defined. According to the resolution in each direction, the bounding box is split into cubic cells and a probe is positioned at the center of each cell. The probe data is arranged in a way that X has precedence over Y, and Y has precedence over Z. This means the order is similar to [x=3 y=2 z=2] -> {000,100,200,010,110,210,001,101,201,011,111,211}.
