/*! \page libpolys_coeffs_page Coefficients for Singular rings and algebras

 Here we implement number arithmetic for some rings/fields (coeff. or number domains): \ref coeffs (Q, ZZ, etc?)

 Generic number is just a void (\ref number).
 Coefficient domains are to be defined by specifying a set of function pointers
 in form of a structure: (\ref coeffs).
