% ### slice
%
% **Syntax**
%
% ```matlab
% % assuming there is a compartment called 'Dendrite'
% x.slice('Dendrite',10)
% ```
%
% **Description**
%
% `slice` partitions a cylindrical compartment into N slices.
%
% The compartment to be sliced must explicitly be a cylindrical
% section, i.e., it must have a defined length and radius.
% `slice` cuts the cylinder along the axis, and connects each
% slice with `Axial` synapses. This object can then be treated
% as a multi-compartment model, and `xolotl` will integrate
% it using the Crank-Nicholson scheme reserved for multi-compartment models.
%
