GNU R easy access to model information for various model objects

 A tool to provide an easy, intuitive and consistent access to
 information contained in various R models, like model formulas, model terms,
 information about random effects, data that was used to fit the model or
 data from response variables. 'insight' mainly revolves around two types
 of functions: Functions that find (the names of) information, starting with
 'find_', and functions that get the underlying data, starting with 'get_'.
 The package has a consistent syntax and works with many different model
 objects, where otherwise functions to access these information are missing.
