Updated the test_delete() unit test.

The diff_tensor object should be removed by the delete() function.

Updated the generic_fns.diffusion_tensor.init() function.

The function now adds the DiffTensorData instance as diff_tensor into the PipeContainer.

Updated the generic_fns.diffusion_tensor.diff_data_exists() function.

The diff_tensor object is now tested for.

Removed the empty diff_tensor structure from the PipeContainer.

This will be added after its initialisation.

Created the data.align_tensor module.

This contains the class and its special methods for the PipeContainer object 'align_tensor'. It
also contains the functions for calculating parameters on the fly.

Bug fix for the align_data_exists() function.

Renamed diff_data_exists() to align_data_exists().

Updated generic_fns.align_tensor to use the modified RelaxTensorError and RelaxNoTensorError classes.

This is to allow for different types of tensors.
