	 * Create a Tree.
	 *
	 * The tree creation API will take nested entries as well. If both a tree and a nested path

	 * new path contents and write a new tree out.
	 *
	 * Parameters fir the tree:
	 *
	 * tree.path
	 *     String of the file referenced in the tree
	 * tree.mode
	 *     String of the file mode - one of 100644 for file (blob), 100755 for executable (blob),
	 *     040000 for subdirectory (tree), 160000 for submodule (commit) or 120000 for a blob
	 *     that specifies the path of a symlink
	 * tree.type
	 *     String of blob, tree, commit
	 * tree.sha
	 *     String of SHA1 checksum ID of the object in the tree
	 * tree.content
	 *     String of content you want this file to have - GitHub will write this blob out and use
	 *     that SHA for this entry. Use either this or tree.sha
	 *
	 * @param   string  $owner      The name of the owner of the GitHub repository.
	 * @param   string  $repo       The name of the GitHub repository.
	 * @param   array   $tree       Array of Hash objects (of path, mode, type and sha) specifying
	 *                              a tree structure
	 * @param   string  $base_tree  The SHA1 of the tree you want to update with new data.
