Gaussian RBF kernel between vertex label histograms

This function calculates a kernel matrix of the Gaussian RBF kernel K_VH,G between vertex label histograms.

CalculateVertexHistGaussKernel(G, par)

`G`	a list of `igraph` graphs
`par`	sigma in the Gaussian RBF kernel

a kernel matrix of the Gaussian RBF kernel K_VH,G between vertex label histograms
