EFA code and report improvements: 1) determine and report EFA model with best fit (criteria: TLI, chi-square, fit); 2) created a boilerplate function to generate a corresponding EFA results comparison table (TODO); 3) updated function that generates EFA model diagrams to support two modes - for main body (best model diagram) and for appendix (all model diagrams); 4) updated EFA report code correspondingly; 5) introduced a project-wide setting in configuration file to control artifacts generation (manuscript's body vs appendix).
