Properly implemented order_parameters.iso_cone_S_to_theta().

The previous order_parameters.iso_cone_S_to_cos_theta() function did nothing.

Reverted r11439 as the sinc function is implemented in numpy.

The command used was:
svn merge -r11439:11438 .

Changed paths:

Implemented the sinc() function.

Shifted to using numpy.sinc() for the frame order equations.

Added 4 more unit tests for the compile_2nd_matrix_*() functions, and modified one of the others.

Converted the isotropic cone frame order model to use the sinc() function.

This removes much round off error and significantly simplifies the equations.

Added a second unit test for perfect order in compile_2nd_matrix_iso_cone().

This checks values at and close to zero, as the sinc() function is differently defined at this
position.

Implemented the sinc() function.

Wrote 4 unit tests for the compile_2nd_matrix_iso_cone*() frame order functions.

Added the maths_fns.coord_transform module to the package __all__ list.

Fixed another 2 trig typo bugs in populate_2nd_eigenframe_iso_cone().

These are the same issue, sin(2.0*tmax)**2 should have been sin(tmax)**2.
