I think just using assemblenears does the exact same thing? It will return a blocksparsematrix which allows linearmaps and MVPs as well. We do not need the HMatrix type for it. |

Add flag skipassemblefars to HMatrix function to build only near field blocks allows to piggyback on the HMatrix implementation to efficiently store linear maps stemming from the discretisation of integral operators of numerically finite reach, such as those with Yukawa kernels or kernels modulated by rapidly decaying envelopes.
