Get the name of the caller method.
Any item that cannot be determined (or is not relevant, e.g. a free
function has no class) is silently omitted, along with an
associated separator.
Parameters
----------
skip : `int`
How many levels of stack to skip while getting caller name;
1 means "who calls me", 2 means "who calls my caller", etc.
Returns
-------
name : `str`
Name of the caller as a string in the form ``module.class.method``.
An empty string is returned if ``skip`` exceeds the stack height.
Notes
-----
Adapted from from http://stackoverflow.com/a/9812105
by adding support to get the class from ``parentframe.f_locals['cls']``
