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.

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

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.

Now saves all chi2 values, to better find reasonable chi level for the Innermost, Inner, Middle and Outer Isosurface.

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

Added the chi_surface=None to the backend function.

When None, it will try to find reasonale chi2 values.
These will define surface levels for the Innermost, Inner, Middle and Outer Isosurface.

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

Added the keyword "chi_surface" to the front-end dx.map function."

To set the chi2 surface level for the Innermost, Inner, Middle and Outer Isosurface.

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

Removed the keywords for "remap" in backend function, since this was not used.
