Represents a single primitive term in the set of all dynamical generators, e.g.
Hermitian operators, for which there exists a map from that generator
to time-evolution by that that generator, through ""EvolutionSet"".
The first element
(Int[], Double[]) is indexes that single term -- For instance, the Pauli string
XXY with coefficient 0.5 would be indexed by ([1,1,2], [0.5]). Alternatively,
Hamiltonians parameterized by a continuous variable, such as X cos φ + Y sin φ,
might for instance be represented by ([], [φ]). The second
element indexes the subsystem on which the generator acts on.

> The interpretation of an `GeneratorIndex` is not defined except

### Examples
Using <xref:microsoft.quantum.canon.paulievolutionset>, the operator
$\pi X_2 X_5 Y_9$ is represented as:
```qsharp
let index = GeneratorIndex(([1; 1; 2], [PI()]), [2; 5; 9]);
