USD: avoid term 'original' in non-CoW context

Instead of 'original object' the code now mentions 'source' or
'duplisource'.

USD: renamed `prune_the_weak` ? `remove_weak_subtrees` + arguments

USD: rename `link` to `dupli_object` and made variable loop-local

I added an explicit `!= nullptr` to make the formatter put the three parts
of the `for`-statement on three different lines (instead of two), which
increases readability.

USD: made `bool weak_export` `const`

USD: removed terminal colour codes

USD: add unit test to test `HierarchyContext::operator<()`

USD: nicer structure for tests/gtests/usd/CMakeLists.txt

This structure makes it easier to add new test source files, and avoids
using a temporary variable.

USD: clarified ownership of objects returned by create_xxxx_writer()

USD: renamed should_visit_duplilink() to should_visit_dupli_object()

USD: clarification of NULL-safety of `get_object_(data_)name`

USD: explicit typedef for `ExportGraph::mapped_type`

USD: clearer explanation of when to override `get_object_data_path()`

USD: clearer explanation of when to override `get_id_name()`

USD: add `_` suffix to non-public member variables

USD: changed C++ to C comments

USD: separate typedef `DupliAndDuplicator`

USD: clarified TODO in AbstractHierarchyWriter

USD: added comment to explain 'instance'

USD: rewrapped comment (change in clang-format config?)

USD: consistent comment style
