def snapshot(folder : Folder) : Snapshot #

Returns a new Snapshot of all files and folders within this folder

  dir.add_file(".keep")
  dir.add_file("README.md")
  dir.add_folder("src") do |src|
    src.add_file("hello.cr")
  end
end
puts LuckyTemplate.snapshot(folder)

{
  ".keep"        => LuckyTemplate::FileSystem::File,
  "README.md"    => LuckyTemplate::FileSystem::File,
  "src"          => LuckyTemplate::FileSystem::Folder,
