WinForm Tab in the right order automatically.cs

private void TabDefault()
{
    // The idea is as a User I expect the Tab Button to go from left to right and from top to bottom. 
    // Unfortunately this isn't the default behaviour in WinForms hence this method.
    // It will go through all Controls and sort them by their x and y coordinates and set a sane set of Tab Indices
    // This saves Maintainence because now you don't need to adapt Tab Indices when you add/remove a control
