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.
