% INPUT
% dataset dataset represented by a structure
% mnem parameter mnemonic
% abortOnError optional logical variable indication what to do in case the
% requested parameter is not found.
% if abortOnError == true the function aborts with an error message
% if no parameter with the requested mnemonic is found
% Default: abortOnError=true
% OUTPUT
% param parameter value
% info three-column cell array with parameter mnemonic, units of
% measurement, and description
param=[];
info=[];
