class_docstr: Class to wrap general DICOM files
  
  Methods:
  
  * get_data()
  * get_pixel_array()
  * is_same_series(other)
  * __getitem__ : return attributes from `dcm_data`
  * get(key[, default]) - as usual given __getitem__ above
  
  Attributes and things that look like attributes:
  
  * affine : (4, 4) array
  * dcm_data : object
  * image_shape : tuple
  * image_orient_patient : (3,2) array
  * slice_normal : (3,) array
  * rotation_matrix : (3,3) array
  * voxel_sizes : tuple length 3
  * image_position : sequence length 3
  * slice_indicator : float
  * series_signature : tuple
