function data = getSurfaceData( userdata, datatype )
% GETSURFACEDATA Returns surface mapping data from userdata
%
% Usage:
%   data = getSurfaceData( userdata, datatype )
% Where:
%   userdata  - see importcarto_mem
%   datatype  - the required data. Must be one of:
%       'act', 'bip', 'uni', 'imp', 'frc'
%   data      - The returned surface mapping data
%
% GETSURFACEDATA Returns surface mapping data from userdata. Data type is
% specified by the `datatype` argument:
%   `act` - activation time
%   `bip` - bipolar voltage
%   `uni` - unipolar voltage
%   `imp` - impedance
%   `frc` - contact force
