a minor error in chebtech? about chebfun

[aaustin141]

Interesting find. The documentation clearly says this should be "cheb1" or "cheb2", but it looks like this doesn't cause problems presently because the "tech" preference from the higher layers gets merged down, and those layers set the preference value to "chebtech1" if necessary.

This should get fixed when we overhaul preferences after the rest of chebfun is in place.

I think this was a change to the code which didn't get followed up in the documentation.

It seems weird to tell the factory method to use the 'cheb1' tech when this is actually called 'chebtech1'.

So from now on, we stick to 'chebtech1' and 'chebtech2' in chebtech.pref and other similar places, right?

@nickhale I think the reason we used "cheb1" and "cheb2" was because, at the time, we were thinking of chebtech as being the tech and the discretization points as being an option or preference.

@kuanxu Yes, I think that's what we will do, but we shouldn't worry about it right this moment, as any changes that get made will probably be overwritten when we go to improve preferences later.
