Probing API 

The preferred API to Ptera’s functionality. It is the most powerful.

`probing()`	Context manager for probing
`global_probe()`	Create a global probe
`Probe`	Probe class returned by probing and global_probe

The Overlay API is more low level than the probing API (the latter uses the former under the hood).

`tooled()`	Transform a function to report variable changes
`is_tooled()`	Return whether a function is tooled or not
`autotool()`	Automatically tool inplace all functions a selector refers to
`BaseOverlay`	Simple context manager to apply handlers corresponding to selectors
`Overlay`	A BaseOverlay with extra functionality
`Immediate`	A handler that triggers when the focus variable is set
`Total`	A handler that triggers when the outer scope for a selector ends

`select()`	Parse a string into a `Selector` object
`transform()`	Transform a function to filter its behavior
