% APPLYMETHOD applys the given method to the input 3D data.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% DESCRIPTION: APPLYMETHOD applys the given method to the input 3D data.
%
% CALL:        d = applymethod(d, pl)
%
% INPUTS:      d      - a 3D data object (xyzdata)
%              pl     - a plist of configuration options
%
% PARAMETERS:
%
%       'method' - the method to apply to the data
%       'axis'   - which axis vector to apply the method to. Possible values
%                  are: 'X', 'Y', 'Z', 'XYZ' [default: 'Z']
%       'option' - any additional option to pass to the method.
