Fixed a bug in plots of coordinate and oblique profiles that was removing the possibility to change coordinate names in plots.
Fixed a bug in examples of the function approxProfileExtrema.
New plotting functions such as plotBivariateProfiles and plotOneBivProfile give a more principled way to visualize bivariate profile extrema functions.
updated univariate profile extrema plotting functions plot_univariate_profiles_UQ for more informative plots.
non-coordinate profile extrema functions are now computed with a faster null-space method.
Fixed many minor errors and bugs.
