Thanks for the merge request!

In general i think this is a feasible workaround. the only thing I am thinking about is, if it would make sense to change the naming schema for the duplicated groupnames. Maybe {groupname}_{group_id}? How does the groupid usually look like?

@MattiasFredriksson does this interfere with #43 in any way?

[MattiasFredriksson]

@AKuederle AKuederle There should be a conflict but there are no functional differences (the KeyError message was updated to be more descriptive).

Otherwise I'm wondering if the name update should be done in this fashion since this is a public method. Not throwing KeyErrors when external code adds a Group could cause silent errors/bugs as it would allow duplicates to be created 'unintentionally'. However, resolving such issues could be done in the future as it would probably complicate the solution a bit.

The standard string formatting currently used is on the form:
'Repeated group name {} modified to {}'.format(name, new_name)

[AKuederle]

I agree! My suggestion would be to hide the overwrite behind a parameter that is False by default

[AKuederle]

I made the changes I suggested above:

1. Made the overwrite optional
2. Changed the rename schmema to be more predictable

@friggog What do you think?

[AKuederle]

@yochaytz Thanks again for the contribuition! I will try to make a new release later today containing this fix.

And @friggog and @MattiasFredriksson thanks for the reviews and the input!
