] | Return an object from a dot path.
Path can either be a full path, in which case the `get_object` function
will try to import the modules in the path and follow it to the final
object. Or it can be a path relative to the object passed in as the second
argument.
Args:
path (str): Full or relative dot path to the desired object
obj (object): Starting object. Dot path is calculated relatively to
this object.
Returns:
Object at the end of the path, or list of non hidden objects if we use
the star query.
Example for full paths::
>>> get_object('os.path.join')
<function join at 0x1002d9ed8>
>>> get_object('tea.process')
<module 'tea.process' from 'tea/process/__init__.pyc'>
Example for relative paths when an object is passed in::
>>> import os
>>> get_object('path.join', os)
<function join at 0x1002d9ed8>
Example for a star query. (Star query can be used only as the last element
of the path::
>>> get_object('tea.dsa.*')
[]
>>> get_object('tea.dsa.singleton.*')
[<class 'tea.dsa.singleton.Singleton'>,
<class 'tea.dsa.singleton.SingletonMetaclass'>
<module 'six' from '...'>]
>>> get_object('tea.dsa.*')

A data row. The keys are either a single column name or a tuple of

non-callable value, 2) a tuple (initial_value, callable), 3) or a
single callable (in which case the initial value is set to an empty
