technically this is v2 bc of how versioning works

• Nav is now NavRail, NavBar and NavTabs
• You can now use <Flex> for flexboxes
• I made <List>
• <SplitButton> now has better types (I am now extending <Button> instead of <button>)
• I remade <Card> so you have more options
• You can now use no-space under size at <Space>
  There is still lots of work to do but I am happy with how development is going!
