Package nom.tam.util

package nom.tam.util

Various commonly used classes for nom-tam-fits. Many of its classes are intended promarily for internal use within the library. It's a bit of catch-all package with all sort of classes thrown in here. Some of these would have had a more natural home in the other packages. A large part of this package provides the IO support for nom-tam-fits, which probably should have deserved its own package. But this is what we have, and we are going to stick with it.
