Class providing native access to FITS images.

Public interface

- tFITSImage
Prerequisite
Etymology
This class provides native access to FITS images. 64bit, 32bit floating point, 32 bit and 16bit integer FITS images are presently supported.
Synopsis
A FITSImage provides native access to FITS images by accessing them with the TiledFileAccess class. The FITSImage is read only. We could implement a writable FITSImage but putting the mask would lose data values (uses magic blanking) and FITS is really meant as an interchange medium, not an internal format.
Because FITS uses magic value blanking, the mask is generated on the fly as needed.
Example
ImageStatistics<Float> stats(im,
logger);
Motivation
This provides native access to FITS images.
