The custom Master Page examples in this folder are all based on the Seattle.master Master Page 
that is included with SharePoint 2013.  This has been included as Seattle_Default.master as a
reference.

The custom Page Layouts in this folder are all based on the BlankWebPartPage page layout that is
included with SharePoint 2013.  This has been included as PageLayout_BlankWebPartPage.aspx as a
reference.

For recipies that include reference to external files (such as images and JavaScript) the files
have been placed in subfolders matching the relative location in SharePoint they should be added
to.  For instance, _catalogs/masterpage/resources should be uploaded to that corresponding 
folder.

When uploading custom Master Page or Page Layouts files and their resources, they should be 
uploaded to _catalogs/masterpage.  This allows SharePoint to see and use them.  In addition, 
resource files uploaded to that location can be included in Design Packages.
