| #### D.2.8.22 hasAlgExtensionCoefficient Procedure from library `ring.lib` (see ring_lib). Usage: hasAlgExtensionCoefficient ( rng ); Return: 1 if the coeffcients are an gelebrai extension, 0 otherwise. Example:
    LIB "ring.lib";
    ring rng = integer,x,dp;
    hasAlgExtensionCoefficient(rng); //no
    ==> 0
    ring rng2 = (0,a), x, dp; minpoly=a2-1;
    hasAlgExtensionCoefficient(rng2);  // yes
    ==> 1
