Purpose: Checks the orthonormality of the SPFs (SPDOs).
          For density operators it checks also the
          hermiticity of the one-particle density operators.
 Usage:   ortho [-f -i -n -r -nofs -ver -h -?] .

Options : 
 -f FILE : The wavefunction (density operator) is read from file FILE rather than from ./psi
           The string FILE may be a relative or a full path-name.
 -i FILE : Same as -f FILE.
 -n step : Compute the orthonormality error only every step-th output.
 -r      : Take the restart file rather than the psi file.
 -nofs  : No transformation to fs. Use when "time-not-fs" was set in mctdh.
 -tr     : For pMCTDH(I), analyse the trace of the SPDOs
 -ver    : Version information about the program 
 -h      : Print this help text.
