[QUANTITY] We do need it then. Some quantities

[martin hill]

Rightio, I think I see where this is going now, cheers all.

What I would like for Christmas is:

* World Co-ordinates (does that count as two quantities which are angles?)
* Brightness (ie flux, magnitudes)

Or are these too high level for discussion at this stage?  

Also:

* Wavelength/Frequency
* Quality... perhaps this is not a Quantity...
* Error

.to start with...

These are I suspect 'Use Cases' rather than general requirements though...
