Added the correct sized graphic for the relaxation dispersion button in the new analysis wizard.

Created some basic graphics for the relaxation dispersion analysis fur use in the GUI.

Expanded the new analysis wizard in the GUI to accommodate the relaxation dispersion auto-analysis.

Now the buttons are a matrix of 4x2 with the NOE, R1, R2, and model-free analyses at the top and two
new blank buttons have been added to the bottom. One will be used for the dispersion analysis.

The relax_disp.select_model user function now checks for the compiled C module when required.

Shifted the standard deviation code from the Monte Carlo error_analysis() function to the lib package.

The new function lib.stats.std() is now used to simplify the error_analysis() function and allow the
code to be reused. This will be useful for expanding the pipe_control.monte_carlo.error_analysis()
function to handle parameters which are dictionaries, for example as in the relax_disp branch.
