Resolves #28, supersedes #330
This brings consistency to the entire project, where much of the existing code already used tabs.
Tabs are a natural choice for indentation. It's semantic, one character per one indent. It's easy to adjust. It's easy to recognize indentation errors where indentation is significant (ie, Python). Especially for this last reason I feel this is one place where PEP8 has made a grave mistake.
Note that this PR is not to debate tabs vs spaces nor PEP8, as maintainer we are decidedly tabs. Comments reserved for reporting missed conversions, regressions, or conflicts.
