Fix for the write_data() function.

The file arg was missing from the write_header() call, and the docstring has been converted to
epydoc format.

Updated the value.write() user function interface to the new design.

Deleted the write() method as it has never been used!!!

Deletion of a number of methods no longer used in the 1.3 line.

These are:
read_columnar_results()
write_columnar_line()
write_columnar_results()

Converted the calculate() method to the new design.

Fixes for the spin container select flag.

Now the flag is always set to the bools True or False rather than 1 and 0.

Modified overfit_deselect() to set the spin container select flag to False rather than 0.

Converted the overfit_deselect() method to the new design.

Fixed the calls to noe.error().

The sample script and system test script now use the spin_id arg rather than residue number.

Converted the noe.error() user function front and back-end to the new design.
