Usage:
primecoeffs(J[,p]); J any type which can be converted to a matrix e.g. ideal, matrix, vector, module, int, intvec
p = integer

Compute:
primefactors <= p of coeffs of J (default p = 32003)

Return:
a list, say l, of two intvectors:
l[1] : the different primefactors of all coefficients of J
l[2] : the different remaining factors

Example:
