              /* Changelog:
Version 1.0.1 / 1.1.0 {Styling}

	1.0.1 - Adding some styling to the columns, possible adding stuff to the rows soon.

	1.0.2 - Nope, the rows haven't changed. The wrapper however has been given some styling.

	1.0.4 - Added back default typography styling to make it look better and added some other styling. Made the background of the wrapper lighter, now only added on desktop, mobile devices will not have this layout (^500px) ! Skipped 1.0.3

	1.0.5 - Added the 'full width column', which is basically a column outside the wrapper. Removed rounded corners from it to make it look good.
	
1.0.7 - Added the 'no-mobile' class, this can be used for wrappers, rows and even specific colums. It will hide until the width >= 500px (Note: the viewport tag will make sure it hides on high-end phones)

1.0.8 - Added the 'sticky' class to make a sticky header out of the first row, try not to use it on multiple rows. Also changed some styling (it's a bit lighter and the corners are a bit less rounded)

1.0.9 - Five new classes 'no-back' which does what is says, it removes the darkened back from the wrapper. And 4 color classes 'warn', 'note', 'error', 'correct'

1.1.0 - Added 7 new classes for wrappers and columns 'rounded' & '.bottom-l/r .top-l/r .rad-l/r'. all of them take care of rounding the corners. Also added the '.hidden-col' class, which makes it invisible, but does not hide it in the debug code, which makes it great for aligning other columns which isn't natively supported in flexbox.
