Based on a coolest object, the Analysis class handles computation of model-independent quantities, including the Einstein radius, mass density slope, effective radius, axis ratio from central moments, etc.
Based on a coolest object, a "composable model" selects the required light and mass model components, and performs lens model computations, including convolution by the PSF, ray-tracing and supersampling.
The plotting routines, separated into different classes, allow the user to visualize the lens models, optionally evaluating the model components on different types of grid (ModelPlotter, MultiModelPlotter), or generate posterior distributions plots (ParametersPlotter).
