function [varargout] = readdump_all(varargin)
% Reads all timesteps from a LAMMPS dump file. 
% Input is dump file name with path
% Output is in the form of a structure with following variables
% .timestep     --> Vector containing all time steps
% .Natoms       --> Vector containing number of atoms at each time step
% .x_bound      --> [t,2] array with xlo,xhi at each time step
% .y_bound      --> [t,2] array with ylo,yhi at each time step
% .z_bound      --> [t,2] array with zlo,zhi at each time step
% .atom_data    --> 3 dimensional array with data at each time step stored
%                   as atomdata(:,:,t)
% Example
%       data = readdump_all('dump.LAMMPS'); 
%
% See also readdump_one, scandump
