[WIP] Recomputation of NrSkewBraces based on definitions.

[olexandr-konovalov]

See "Skew braces and the Yang-Baxter equation"
by L. Guarnieri, L. Vendramin for definitions
(https://arxiv.org/abs/1511.03171)

For example:

gap> for i in [2..15] do 
> Print(i,":",NrSmallBraces(i),":\c");
> Print(NrBracesFromScratch(i),":\n");
> od;

This is work in progress - I plan to incorporate into testing to calculate some numbers of braces "on fly" and compare with the stored ones.
