1313e/PRISM: v1.2.0

This is the v1.2.0 release of the PRISM package.

New additions:

• The PolyLink class was added to PRISM's standard ModelLink subclasses;
• Introduced the new 'req_n_walkers' input argument for the get_walkers() function, which can be used to generate a specific number of required walkers using a custom Metropolis-Hastings algorithm;
• Added the get_bibtex() function, which prints the BibTeX entry for citing the PRISM paper;
• Added Crystal, PRISM's Projection GUI; Crystal can be used to more easily create; draw; compare; and analyze projection figures;
• It is now possible to use nested worker modes;
• It is now also possible to make calls to solely workers using the new _make_call_workers() method;
• Finally, one can now make calls using rank-specific attributes.

Bugfixes:

• Fixed a bug where if one tries to reconstruct the first iteration of the emulator using less data points than before, the emulator would not be reset properly;
• Fixed a bug where analyzing a finished iteration through construct() would not work properly in MPI;
• Fixed a bug where sometimes the check_vals() function would not raise a proper error.

Changes/Optimizations:

• Added several tests to various different functions/methods to make sure that the layouts of provided arguments are correct;
• PRISM's colormaps have been ported to *e13Tools';
• The 3D line-of-sight depth plots now use the 'freeze' colormap (new colormap in e13Tools);
• All projection hypercube tuples now also carry the iteration for which they were made;
• The default names of projection hypercubes have been changed slightly;
• Rewritten the worker mode of PRISM into the WorkerMode class;
• Removed all deprecated features from v1.1.
