Description
https://github.com/Macaulay2/M2/blob/86d6c70f8746e6b13d95c53ad20d880e0d60a8dc/M2/Macaulay2/m2/quotring.m2#L9-L12
It would make sense if, for instance, `isQuotientRing(QQ[x,y]/x)` returned false after flattening the ring, but as it is implemented it seems pointless and counter-intuitive:
```m2
i3 : isQuotientRing (ZZ/3)
o3 = true
i4 : isQuotientRing (ZZ/3[x])
o4 = false
```
I say pointless because it might as well not be a method at all:
```m2
isQuotientRing = R -> class R === QuotientRing
```

Research direction
Read M2/Macaulay2/m2/quotring.m2 at lines 9-12 and reproduce the examples for ZZ/3 and ZZ/3[x]. The issue does not specify an agreed behavior or named tests, so first determine the intended definition of isQuotientRing; done requires that behavior to be settled and covered by tests.
