Code style guide

Basically, the code style is compatible with Julia.Base, which follows much of the rules that is also popular in other languages.

Whitespaces

Always surround these binary operators with a single space on either side: assignment (=), augmented assignment (+=, -= etc.), comparisons (==, <, >, !=, <>, <=, >=, in, not in, is, is not), Booleans (and, or, not)
No white spaces immediately inside parentheses, brackets or braces.

No:  sum( 1), sum(1 ), sum( 1 )
