RainLayout is a multi-purpose LayoutManager.
Mainly it can be used like BoxLayout to stack components in horizontal or vertical direction.
However RainLayout can much more then BoxLayout:

• easy switch between horizontal and vertical orientation
• Components can be layed out in one row or in multiple rows
• ordering of Components according to Comparator provided by target Container
• row hiding: show only one row and hide all other rows
• reverse Components and/or rows order

RainLayout has 5 policies which affects how components layed out and how computed preferred size:

• RainLayout.LAYOUT_POLICY_COMPUTE - preferred size is computed
• RainLayout.LAYOUT_POLICY_ASK - width of target Container used as preferred width (horizontal orientation) or height of target Container used as preferred height (vertical orientation)
• RainLayout.LAYOUT_POLICY_EXPLICITE_PIXELS - width (in pixels) was explicitly set (horizontal orientation) or height (in pixels) was explicitly set (vertical orientation)
• RainLayout.LAYOUT_POLICY_EXPLICITE_COLUMNS - column count was explicitly set (horizontal orientation) or row count was explicitly set (vertical orientation)
• RainLayout.LAYOUT_POLICY_TABLE - same as LAYOUT_POLICY_EXPLICITE_COLUMNS, but layed out as table.

Following constraints can be used to add Components:

• RainLayout.GROW (Component can grow),
• RainLayout.SHRINK (Component can shrink),
• RainLayout.FLEX (Component can shrink and grow) and
• RainLayout.FIXED (Component can neither shrink nor grow)
