relax SVN archive

Created the lib.mathematics relax library module.

This currently contains two functions, order_of_magnitude() and round_to_next_order().

Removed the numpy dependence from the manual C module compilation script.

Redesign of the relaxation dispersion models in the relax_disp.select_model user function front-end.

The models have been renamed and better defined based on the experiment type (CPMG or R1rho).

The relax_fit C module setup() function now uses the Py_RETURN_NONE macro to terminate.

This macro does exactly what the old code does anyway.

Increased the maximum number of relaxation times for the relax_fit C module to 50.

Shifted the C array creation to the relax_fit C module header.

The params, values, sd, relax_times, and scaling_matrix C arrays are now declared and allocated in
the header file rather than using malloc() calls in the setup() function. This is to attempt to
remove a memory leak. The arrays are now of fixed length and reused for each setup() call. These,
as well as the other variables declared in the header are no longer declared in the functions.

Improved the Python and C documentation of the functions of the relax_fit C module.

Converted the Py_BuildValue() calls to PyFloat_FromDouble() in the relax_fit C module.

This doesn't change much.

The numpy include is no longer used for the compilation of the C modules.

Numpy is not used at all in the C modules, so this just adds an annoying dependency for those who
need to compile the module themselves.

Removed some bad calls to status.exec_lock.release().

This commit may have to be reverted in the future. The problem is that the execution lock is not
being held when these calls are made. The calls were added as a kludge to handle certain situations
where the execution lock was not released. There may be cases were this behaviour is still needed.

Big bug fix for a memory leak in the relaxation curve-fitting C module.

Proper reference counting is used for the temporary 'element' Python objects used in the conversion
between Python and C objects. The use of the Py_CLEAR() macro removes the memory leak. However the
number of references as seen by sys.gettotalrefcount() in a debugging Python version keeps rising
and might be a problem in the future.
