quiverWeights QThis method returns the weights of the provided toric quiver. The weights are the image of the quiver flow under the inc map, which is defined as $$ \text{inc}(\mathbf{w})(i) := \sum_{a\in Q_1 \atop a^{+} = i} \mathbf{w}(a) - \sum_{a\in Q_1 \atop a^{-} = i} \mathbf{w}(a) \quad \text{ for all } i \in Q_0. $$ where for any arrow $a\in Q_1$, we denote its head as $a^{+} \in Q_0$ and its tail as $a^{-} \in Q_0$.
