DOT to PseudoC converter.

[maximumspatium]

This is the first shoot at DOT->PseudoC conversion tool, see #32

Parsing of DOT files is delegated to dot_tools library to avoid unnecessary script complexity and corner cases. dot_tools requires Python 2 which is IMHO a bearable inconvenience for such a tool.

While there is still room for improvement, the tool produces correct output for two sample graphs supplied in the test_graphs directory. One of them is part of ScratchABlock test suite.

It's not clear whether any ENTRY node should be handled appropriately. For the moment being, such a node is simply ignored.

Line numbering is zero-based even if the first node is labeled as "1". This was done to support letter-based node labeling, i.e. "A, B, C, D" etc...

Thanks for the patch!

I'm not sure if that's obvious, but I'm trying to avoid adding external dependencies. PyYAML is the only one for runtime, plus nosetests for testing. I didn't mentioned that, because I didn't think that external library would be required to parse lines with the format like A -> B -> C.

So, it brings dependency not just for external library, but for a whole different language version.

Anyway, that's indeed just external convenience tool. Thanks for working on that, merged.

I fully agree with you. On the other side, you've requested a "pretty simple script". Reimplementing DOT parsing without external dependencies is feasible but goes beyond simple scripts. I think we should spend our time doing more important developments.
