qstr: Graphical display of object structure

In qtutils: Miscellaneous Qt-based utilities

Description

qstr creates a widget displaying the structure of an arbitrary R object. The default method simply shows the output of print(x) in a text area. Table like objects are shown using qdataview.

The methods for lists and environments allow recursive examination of elements using a QSplitter. The method for environments allows a simple REPL to be started with the correspoding environment as its evaluation environment.

qbrowser leverages the list method to provide a simple object browser. qrecover similarly provides a graphical replacement for recover, and may be used as the "error" option for interactive debugging.
