Consider adding support for tracking subclass method invocations #142
Description
An issue arose when analyzing GeoPandas and its consumption of Pandas APIs.
GeoPandas subclasses Pandas (see here), so, in principle, a subclassed method should correspond to an equivalent Pandas DataFrame method. However, this is not the case.
Based on analysis, GeoPandas appears to only consume 3 Pandas APIs, but this is, presumably, not a fair representation, given that many a GeoPandas DataFrame method is a Pandas DataFrame method.
Accordingly, may be worth investigating whether we can track subclass method invocations.
In conversation with @saulshanabrook, he suggested updating the Tracer to look at method resolution order (MRO).
