Started the modification from 'devnull' to tempfiles.

This is as proposed by Edward d'Auvergne to catch the creation of a well formatted and non empty
tensor pdb file and was discussed in a post at:

Overhaul of the chi-squared gradient and Hessian functions.

The original functions have been renamed to dchi2_element and d2chi2_element as these calculate the
gradient for element j and the Hessian for element {j, k}. Two new functions, dchi2 and d2chi2 have
been written to calculate the full gradient and Hessian in one function call.

These changes will temporarily break a lot of code!
