Created the new minimise.grid_zoom user function.

This allows the grid zoom level to be set. The value is stored in the current data pipe and will be
used later by the minimise.grid_search user function.

Redesign of the optimisation user functions calculate, grid_search, and minimise.

In preparation for expanding the number of optimisation user functions, these three current user
functions have been shifted into the new minimise user function class. The calculate user function
is now accessed as minimise.calculate. The grid search as minimise.grid_search. And minimisation
is via the minimise.execute user function. The icon used for the new user function class is the
Rosenbrock function or the banana optimisation problem.

As this is such a radical change, a huge number of changes in the relax source code, the sample
scripts, the user manual, and the test suite were required.

Added the missing timing module to the relax library package __all__ list.

Added the missing timing module to the relax library package __all__ list.

Added a new set of icons for use with the minimisation user functions.

These are of the Rosenbrock function and are much better suited for small icons than the current
OpenDX 3D isosurface plots. The matplotlib figure originates from public domain code at
http://commons.wikimedia.org/wiki/File:Rosenbrock_function.svg.

Creating a branch for attempting to implement zooming grid searches.

Updated the frame order optimisation results for the CaM missing data free rotor test data.

The optimisation in the frame_order.py is now of higher precision with the number of Sobol' numeric
integration points significantly increased, especially for the Monte Carlo simulations. The new
frame order representation files have been added to the repository, as well as the intermediate
state files.

Created the time user function.

This is just a shortcut for printing out the output of the time.asctime() function.
