Improvement to Community User/Contact Creation Script & NetworkMemberGroup Transform

[Julian88Tex]

A number of suggestions were made on PR #10 about ways to improve Community User/Contact Creation Script that should be considered:

• verify uniqueness of usernames for each user creation to prevent attempting to create the same username twice
• look into using an fstring for line creations
• switch cci python class task usage from BaseSalesforceApiTask to just BaseTask
• consider using a list for all profiles/permission sets in transform file
• consider using the enumerate function for counting
• look into less risky ways of creating and/or deleting the dataset load file

For more details on these suggestions, refer to PR #10.

Also: if you're going to copy files, you could probably use this task:

But I still think it would be better to not do "resetting" at all. Templates can be immutable and and outputs don't need to be reset.
