V1.1.0

Major recode and better performance now since for similar widgets (same column, row, columnspan, rowspan) they can share frames.

Please update whenever it shouldn't break any code unless you use FlexBoxFrame.StrictFrameGrid
Also you will need to rename FlexBoxFrame to FlexBoxPage

V1.0.1

Added margin option to FlexBoxFrame.place_widget()

You can now pass an integer, tuple length 2, 3 or 4 as the margin= option and will apply that margin inside the Framefor whatever your trying to put inside. This does mean that you can place multiple objects inside one frame though I wouldn't recommend it as I haven't tested it.

v1.0.0

First release ever, will slowly add different flexbox styling options but for now you will have to add margins etc manually! sorry :(
