Use consistent coding style

[santigimeno]

Hi,

This is more of a personal request. The coding style is not consistent throughout the code and specially the use of tabs/spaces and different indentation values annoys me every time I read and try to modify the code. Would it be possible we define some basic guidelines: indentation, tabs/spaces, etc.? I would happily modify the code if we can agree on that.

Thanks in advance!

Would be good to have, but I'll probably prefer coding style in the form of script I can run or set as commit hook rather then verbal guidelines ( using something like https://github.com/Constellation/escodegen )
