docs: Convert the array to a one-hot array with walues 0 and 1 for each entry<br>
  If input has shape [ a, ..., n] then output has shape [ a, ..., n, depth],
  with out[i, ..., j, in[i,...,j]] = 1 with other values being set to 0
  
  @param name    Output variable name
  @param indices Indices - value 0 to depth-1
  @param depth   Number of classes
  @return Output variable
