 Usage:  x = invfwtin (ti, d, h)  
 
 Input:

  ti                     n x d matrix, the wavelet coefficients of all circular shifts, 
                         can be retrieved by fwtin. n has to be a power of 2 
                         
  d                      integer, the level for the father wavelets s.t. 2^d is the 
                         number of father wavelet coefficients 
                         
  h                      m x 1 vector, wavelet basis 
                         
 Output:

  x                      n x 1 vector
