Added the framework for system tests for supporting NMRView within relax.

Addition of an NMRView peak list for use in the relax test suite.

This file originates from Ryan Hoffman (https://gna.org/users/rydog). It can be found attached to
bug #11913 (https://gna.org/bugs/index.php?11913) within the 'convert.tgz' archive
(https://gna.org/bugs/download.php?file_id=4488) as the debug.xpk file.

Created a directory for holding peak lists for the test suite.

Corrected an error in the definition of eta.

This difference arises from a different definition of the constant c... Basically, this only affects
the obtained F_eta value by dividing it by a factor of sqrt(3) independent of the magnetic field.
Hence, consitency evaluation was fine before this correction, except that values were multiplied by
sqrt(3).

Also, the test-suite values for F_eta were changed so the test still passes.

These changes follow a thread started at:

Improved the diffusion tensor system tests.

Moved the PDB and sequence loading with the rest of the diffusion tensors initialization and
uncommented the sphere and spheroid parts of the structure.create_diff_tensor_pdb() function test.

Added a missing import.

Added the loading of a sequence for the corresponding PDB.

Corrected a path from relative to absolute.

Corrected a test for the loading of a PDB.

This is one step towards the structure.create_diff_tensor_pdb() function working.

Added a test within the diffusion tensor system tests.

This one tests the structure.create_diff_tensor_pdb() function.
