#24 Margin specification in `aim/Test`

[Gustav W Delius]

Consider the following question:

t> Please enter $\pi$ to 20 decimal digits.
s> [ ans -> `aim/Test`(ans,eval (Pi,20),
numeric,`sf`=20),
evalf(Pi,20)]

This produces the teacher's answer
3.1415926535897932385 but marks an answer of
3.1415926535 as correct as well.

This is because Digits is by default 10.

> Digits := 20:
> `aim/TestNumeric`(eval (Pi,20), 3.1415926535, 'sf'=10);
false

I think that `aim/TestNumeric` should set Digits for itself so
as to produce the expected behaviour. It will probably need
to declare its arguments as 'uneval' and only evaluate them
after setting Digits. But there might be some pitfalls with
this that I haven't thought of.
