NSGSC: Calculate quantum computing graph states

NSGSC (Not Sexy Graph State Calculator) can calculate graph states that represent multi-qubit in quantum computing.

In quantum computing, a graph state is a special type of multi-qubit state that can be represented by a graph. Each qubit is represented by a vertex of the graph, and there is an edge between every interacting pair of qubits. In particular, they are a convenient way of representing certain types of entangled states.

Graph states are useful in quantum error correcting codes, entanglement measurement and purification and for characterization of computational resources in measurement based quantum computing models.
