Created branch for the testing of speeding up dispersion analysis.

This can be a disruptive process, and needs its own branch.
This branch can then be tested for speed against trunk.

task #7793:(https://gna.org/task/?7793) Speed-up of dispersion models.

Moved numpy_future from lib to extern.

Extern is special package for external software or code that is bundled with relax.

task #7792: (https://gna.org/task/?7792) Make the dx.map write suggest chi surface values.

Added "numpy_future" to the __init__.py file in lib directory.

task #7792: (https://gna.org/task/?7792) Make the dx.map write suggest chi surface values.

Added lib/numpy_future.py.

This module is for implementing numpy function code from higher versions of numpy.

The relax dependencies listed at the download page of relax:
http://www.nmr-relax.com/download.html#Source_code_release
currently only requires Numpy v. 1.0.4.

task #7792: (https://gna.org/task/?7792) Make the dx.map write suggest chi surface values.

Changed the percentage which is different in percentile from numpy_future.

task #7792: (https://gna.org/task/?7792) Make the dx.map write suggest chi surface values.

Changed the import of percentile from lib.mathematics to lib.numpy_future.

task #7792: (https://gna.org/task/?7792) Make the dx.map write suggest chi surface values.

Fix for systemtest Relax_dips.test_cpmg_synthetic_dx_map_points.

Removing keyword "remap", since this is not in use anymore.

task #7792: (https://gna.org/task/?7792) Make the dx.map write suggest chi surface values.

Reverted r23140 as this violated the license of http://code.activestate.com.

The recipe, was a function to compute the percentile of range of values.
This is because that numpy.percentile is first introduced in 1.6?

The recipe was from:
http://code.activestate.com/recipes/511478-finding-the-percentile-of-the-values/.

The command used was:
svn merge -r23140:23139 .

.....
Added mathematics functions to lib/mathematics.py to calculate percentile.

This is because percentile is only available in numpy 1.9.

task #7792: (https://gna.org/task/?7792) Make the dx.map write suggest chi surface values.

Modified:
trunk/lib/mathematics.py
.....

Increased the precision of many of the Frame_order.test_rigid_data_to_*_model system tests.

This is to fix a test which was failing due to the recent re-parameterisation of the rotor frame
order model to eliminate one parameter. The precision of the numeric Sobol' sequence integration
has been increased by shifting the fixed parameter values even closer to zero. As a consequence,
the chi-squared value of five of these tests is now lower.

Made the standard values of chi2 surface be 10, 20, 50 and 90 percentile of all chi2 values.
