Blackbox FMM in 2D using Matlab

This is the MATLAB/Octave translation of the C++ code of bbFMM. Tested with Matlab R2016.

Define the kernel in @ExampleKernel1/ExampleKernel1.m file or create your own class. Use the kernel in the FMM_Main.m file to compute the corresponding potential. Maybe used for multiple kernels simultaneously without having to rebuild the tree.

The code outputs the FMM tree object and the potential, resulting from the kernel-matrix to charge-vector multiplication.
