This module is NOT meant to be directly imported! It has been designed such
that it can be bootstrapped into Python as the implementation of import. As
such it requires the injection of specific modules and attributes in order to
work. One should use importlib as the public-facing version of this module.

ModuleSpeca The specification for a module, used for loading.
A module's spec is the source for information about the module. For
data associated with the module, including source, use the spec's
loader.
`name` is the absolute name of the module. `loader` is the loader
to use when loading the module. `parent` is the name of the
package the module is in. The parent is derived from the name.
`is_package` determines if the module is considered a package or
not. On modules this is reflected by the `__path__` attribute.
`origin` is the specific location used by the loader from which to
load the module, if that information is available. When filename is
set, origin will match.
`has_location` indicates that a spec's "origin" reflects a location.
When this is True, `__file__` attribute of the module is set.
`cached` is the location of the cached bytecode file, if any. It
corresponds to the `__cached__` attribute.
`submodule_search_locations` is the sequence of path entries to
search when importing submodules. If set, is_package should be
True--and False otherwise.
Packages are simply modules that (may) have submodules. If a spec
has a non-None value in `submodule_search_locations`, the import
system will consider modules loaded from the spec as packages.
Only finders (see importlib.abc.MetaPathFinder and
importlib.abc.PathEntryFinder) should modify ModuleSpec instances.

To indicate that the module is a package, set
submodule_search_locations to a list of directory paths. An
empty list is sufficient, though its not otherwise useful to the
import system.
The loader must take a spec as its only __init__() arg.

being made from, and the level adjustment.
This function represents the greatest common denominator of functionality
between import_module and __import__. This includes setting __package__ if
the loader did not.

The import_ parameter is a callable which takes the name of module to
import. It is required to decouple the function from assuming importlib's
import implementation is desired.

The 'globals' argument is used to infer where the import is occuring from
to handle relative imports. The 'locals' argument is ignored. The
'fromlist' argument specifies what should exist as attributes on the module
being imported (e.g. ``from module import <fromlist>``). The 'level'
argument represents the package location to import from in a relative
import (e.g. ``from ..pkg import mod`` would have a 'level' of 2).

modules, those two modules must be explicitly passed in.
