* Clean up identation of the whole program by replacing spaces with tabs. Python is an inherently ugly and unclean language, most infamous its use of in dentation to control semantics. Previously, the program used a very inconsistent number of spaces for that indenting, which easily lead to bugs IMHO and made maintenance much more difficult. Now, tabs show the identaiton level of a line (and therefore where it belongs to) and spaces are only used to vertically arrange something (which belongs however to the same identation level). * Apart from cases where I found it usefule (e.g. large structs), resolved line continuations. All people (should) have powerful editors, which are capable of doing automatic line wrapping if wanted. Its not the business of the programmer to take care on this, especailly in text blocks, where it’s really annoying to insert something and then need to re-wrap everything in shape. * Cleaned up some spelling of the """ doc comments. * Further minor cosmetic changes.
