[fitsbits] Axis units

[Tom Kuiper]

Greetings all.

It seems to me that in addition to the venerable keywords
CTYPEn CPIXn CVALn CDELTn and CROTAn, one needs to specify the units for
the axis values.  CTYPn, for example, may specify FREQ, but is it Hz, MHz,
etc.?

I've temporarily invented CUNITn until someone corrects me or improves on
it.

Thanks and regards

Tom
