Added a script and results files for the base 'R2eff' model for Remco Sprangers' ClpP data.

Simplified the Relax_disp.test_sprangers_cpmg_data_auto_analysis system test script.

The pA and kex parameters are now also pre-set to speed things up.

Changes to the Sprangers ClpP data analysis script.

Manually reverted the temporary change of r21094.

The command used was:
svn merge -r21094:r21093 .

Temporarily turned off the Relax_disp.test_sprangers_cpmg_data_auto_analysis system test.

This commit must be reverted!

Modified the Relax_disp.test_sprangers_cpmg_data_auto_analysis system test so the models are programatically changed.

Replaced all usage of scipy.linalg.expm() with lib.linear_algebra.matrix_exponential.matrix_exponential().

This is for the functions of the lib.dispersion package used for the relaxation dispersion numeric
solution models. The change eliminates a bug in the scipy function which uses the Pade
approximation which fails horribly for the complex part of the matrix. The real part looks good,
but the complex part looks to have nasty truncation artefacts which is propagated and amplified
through the Bloch-McConnell equations.

Fix for the new lib.linear_algebra.matrix_exponential.matrix_exponential() function.

This function now returns a numpy array type rather than matrix type.

Created the lib.check_types.is_complex() function.

This is used to determine if a number is a Python or numpy complex type.

The lib.linear_algebra.matrix_exponential.matrix_exponential() function now uses lib.check_types.is_complex().

This fixes the function for complex matrices.
