Duplicated 5 systems tests of the internal PDB reader for the Scientific python PDB reader.

A small fix to the system test.

However, is this fix the solution or is there something wrong with the reading of data (such as
'R2eff') by relax_data.read() ?

Shouldn't the data, for example 'R2eff', be available in 'cdp.mol[0].res[0].spin[0].R2eff_val[0]'
or 'cdp.mol[0].res[0].spin[0].R2eff[0]' for the 1st spin of the 1st residue in the 1st molecule ?

Wrote 2 new system tests for the new structural data design.

In test_read_pdb_internal6(), 2 different structures are loaded as 2 molecules. In
test_read_pdb_internal7(), 2 identical structures are loaded as 2 molecules.

Added a missing import.

Added more to the docstring.

This is not complete yet...

Reordered a few functions for alphabetical reasons.

Removed the obsolete function 'relax_disp.r2eff_read()'.

R2eff values will be read directly by 'relax_data.read()' (see r8702 and r8703).

Fixed an annoying bug in the RelaxError debugging mode.

The problem here is that the relax state was being saved in the __init__() methods if in debug mode.
The result was that in try statements which catch and allow for RelaxErrors, the relax state was
being saved even though the error message and exception was suppressed. The fix was to shift the
state saving code into the __str__() method.

A side effect of this change is a simplification of all the RelaxError classes as the debug code is
no longer duplicated in each class.

Modified __base_data_types() to include NOE restraints.
