* GA-149 | initial commit

failing for now

* checkpoint

no new tests yet, just experimenting with `AdjListInnerDict`

* checkpoint 2

* checkpoint 3

still no new tests, just brainstorming

* checkpoint 4

starting to get messy...

* cleanup & comments

* comments

* cleanup: `__contains__`

* cleanup: `__getitem__`

* new helper functions

* checkpoint 6

* checkpoint 7

* cleanup

* add warning

* fix: conditional override

* fix: func name

* new: `FETCHED_ALL_IDS`

Attribute used to establish if all ArangoDB IDs have been retrieved for the particular dict class. Not to be confused with `FETCHED_ALL_DATA`, which fetches both IDs & Documents

* fix: parameterize `EDGE_TYPE_KEY`

* cleanup: redundant code

* fix: `nodes` & `edges` properties

* new: `__process_int_edge_key`

* new: `test_multigraph_*_crud`

minimal suite for now. need to revisit

* update: `test_algorithm` for `nxadb.MultiGraph`

* fix: `__get_mirrored_adjlist_inner_dict`

* extra docstring

* new: graph overrides

* fix: EdgeKeyDict docstring

* update `phenolrs` wheel

* fix: phenolrs

* remove unused import

* fix: except clause

* fix: logger info

* remove multigraph lock

* fix: typo

* cleanup: kwargs

* remove print

* fix: add `write_batch_size` to config

this will be useful for bulk updates

* temp: `NodeDict.update` hack

Just a temporary solution. Will be removed shortly

* revert ec1cbc8

* add custom exception

* update node & edge type logic for new vs existing graphs
