The enable_errorist() is automatically called on package start to
inject handlers for warnings and errors. When the package is unloaded,
disable_errorist() is called to remove warnings and errors. If you
wish to disable warnings or error individually, please use either
disable_error_shim() or disable_warning_shim().

Add or remove a listener to top-level task callbacks that checks for whether a new warning or error occurs and then triggers a search browser.

By default, both enable_warning_shim() and enable_error_shim() functions
are automatically triggered when the errorist package is loaded.
The error shim uses R's default handler for errors set by specifying
a function for error in options().
For the warning shim, a top-level task callback added to the environment
via base::addTaskCallback(). This causes the warning handler to fire
each time a new function call occurs in R regardless of whether it
triggers an error.
