Modified the NH bond length to be 1.041 Angstrom.

This is from Ottiger, M. and Bax A., J. Am. Chem. Soc. (1998), 120, 12334-12341.

Added a debugging print out.

Modified the print out to remove the broken Eigenvalue sum and add the Saupe order matrix.

The RDC data is now formatted for Pales, to check the synthetic test model and relax.

Modified how the generic peak intensity file is detected.

The change is that if no other formats are detected, relax falls back to the generic format.

When finding attached atoms, the radius of atoms assumed to be bonded has been increased to 2 Angstrom.

Some fixes for the test_read_pdb_internal1() and test_read_pdb_scientific1() system tests.

Added the Ca atom of GLU 3.

Removed some debugging print outs.

Debugged the __minimise_bc_data() method.

The calculated Q-factors for the RDC and PCS were completely incorrect!
