post_proc(chain, theta_gt, feature_filter, fem_mat, energy_func, fig_title, fig_title2, fig_dir = None, plotting=True, interactive_job=True):
Making output plots containing a summary of the chains, and the corresponding predicted energies
Input Arguments
-chain - object of Chain class (see core_spike_slab file)
-theta_gt - The true set of feature coefficients for the benchmark material
-feature_filter - The list of features to retain for constructing the Markov chain. Suppressed features will be highlighted with a red patch in the plot
-fem_mat - The name of the benchmark material to be tested
-energy_func - The label of the function used to predict energy evolution for the discovered material along 6 different deformation paths
-fig_title - Title displayed on the figure
-fig_title2 - Filename of the saved figure (.png format)
