-Style guidelines
-----------------
-
-You'll need to follow the subsequent rules in order to get your code merged:
-
-* Use Allman_ style for block braces.
-* No space before `(`
-* Add space after each `(` and before each `)`
-* Use braces single line statements
-* Don't use mixed case naming style, use underscores instead.
-  Bad example:
-
-    int myAwesomeVariable = 0;
-    doSomething( myAwesomeVariable );
-
-  Good example:
-
-    int my_awesome_variable = 0;
-    do_something( my_awesome_variable );
-
-* Don't vertically align tokens on consecutive lines.
-* If you break up an argument list, align the line to opening brace
-* Use 2 space indentation (no tabs)
-* Use spaces around operators, except for unary operators, such as `!`.
-* Add LICENSE header in new files you create.
-* Put vim modeline as the first line of file header
-* Use the lower-case for CMake commands
-* Do not add trailing whitespace
