Current version of Collection on pypi throws exception if one checks if a document exists

[larsborn]

Mainly putting this in here if someone is running into similar issues.

The collection objects on version 1.3.1 (most recent version pf pypi by the time of writing) throws a KeyError exception when one checks for document existence:

if my_key in db['my_collection']:
    [...]

Intended behavior would imho be to gracefully return False if the document does not exist. This behavior seems to be already implemented in the more recent version 1.3.2. through a new __contains__ method on the Collection class. Resolving #105 would solve this issue.

A current workaround obviously is:

exists = True
try:
    my_key in db['my_collection']
except KeyError:
    exists: False
if exists:
    [...]

Potentially related #113.

Yes is has been implemented in the 1.3.2 but only with the document key. I could improve it to also work with the document itself.

Cheers!
