* formatting change, no logical change

* formatting and name change, no logical change

* [refactor] sha1_store's path arg

- make sha1_store's path arg directly the path, not its parent
- this is because sha1_store is not like a .git or a .wgit dir, which is
  nested inside another "working" dir. It is simply a store, which
  is using a given dir.
- updated repo and tests as well.

* remove a test warning due to deprecated API from torch

* [refactor] change how dot_wgit_dir_path is used

- it should only be assigned in __init__.
- we use it in error checking in the rest APIs.

* simplify the init a bit

* refactor the sanity check

* moved some functions, no code change

* [feat] added per-tensor add to the repo

* enabled gzip compression on add

* fix a unit test

* add a note

* make sha1 store work on general dict

* handle general state_dict from a model, not just a module's one-level OrderedDict

* formatting
