This patch adds the option to provide as vect_distance strings like "norm-3", "norm-6", "norm-2" (same as the default) and "norm-inf", besides "euclidean" when creating the SOM (norm-p with any positive real p). For example:
som = somoclu.Somoclu(n_columns, n_rows, compactsupport=False, vect_distance="norm-6")
This is supported with kerneltype = 0 only, at the moment (the GPU kernel uses an optimized implementation tied to p=2, but in the future it might be possible to add in denseGpuKernels.cu, alongside the current implementation, an alternate one if norm-p is specified).
