20:41 CoCoALib Feature #1210 (Closed): New Fn: make public "coefficients" (of poly wrt a given PP basis)

I have opted for the KISS solution -- we can make fancier versions in the future is there is need for them!
I have c... John Abbott

Nico Mexis asked whether there could be a check for interrupts inside the factorizer.
This will much easier to achie... John Abbott

19:48 CoCoALib Design #1693 (Resolved): SizeInBase: obsolete

Anna agreed.
I have moved the code to @obsolete.H@ and @obsolete.C@ (from BigIntOps@).
All tests pass.

I think *@SizeInBase@* is not really useful (cannot think of any situation).
Also it can easily be implemented by ca... John Abbott
