| #### D.2.12.22 hasTransExtensionCoefficient Procedure from library `ring.lib` (see ring_lib). Usage: hasTransExtensionCoefficient ( rng ); Return: 1 if the coefficients are rational functions, 0 otherwise. Example:
    LIB "ring.lib";
    ring rng = integer,x,dp;
    hasTransExtensionCoefficient(rng); //no
    ==> 0
    ring rng2 = (0,a), x, dp;
    hasTransExtensionCoefficient(rng2);  // yes
    ==> 1
    ring rng3=(49,a),x,dp;
    hasTransExtensionCoefficient(rng3);  // no
