Detailed Description

A struct passed back and forth between Exposure and ExposureInfo when writing FITS files.

An ExposureInfo is generally held by an Exposure, and we implement much of Exposure persistence here in ExposureInfo. FITS writing needs to take place in three steps:

1. Exposure calls ExposureInfo::_startWriteFits to generate the image headers in the form of PropertyLists. The headers include archive IDs for the components of ExposureInfo, so we have to put those in the archive at this time, and transfer the PropertyLists and archive to the Exposure for the next step.
2. Exposure calls MaskedImage::writeFits to save the Image, Mask, and Variance HDUs along with the headers.
3. Exposure calls ExposureInfo::_finishWriteFits to save the archive to additional table HDUs.
