-# Layout - layouts follow a pattern like this:

-# [[row.child]] represents either a widget or a column.

-# All layout components have a ratio value - if this is not set, then it defaults to 1. 
-# The default widget layout:
-#[[row]]
-#  ratio=30
-#  [[row.child]]
-#  type="cpu"
-#[[row]]
-#    ratio=40
-#    [[row.child]]
