Create a tree

 The tree creation API will take nested entries as well.
 If both a tree and a nested path modifying that tree are specified,
 it will overwrite the contents of that tree with the new path contents
 and write a new tree out.

 @param [Hash] params
 @input params [String] :base_tree
   The SHA1 of the tree you want to update with new data
 @input params [Array[Hash]] :tree
   Required. Objects (of path, mode, type, and sha)
   specifying a tree structure

 The tree parameter takes the following keys:
 @input tree [String] :path
   The file referenced in the tree
 @input tree [String] :mode
   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
 @input tree [String] :type
   Either blob, tree, or commit
 @input tree [String] :sha
   The SHA1 checksum ID of the object in the tree
 @input tree [String] :content
   The content you want this file to have - GitHub will write
   this blob out and use the SHA for this entry.
   Use either this or <tt>tree.sha</tt>

 @example
  github = Github.new
  github.git_data.trees.create 'user-name', 'repo-name',
    tree: [
      {
        path: "file.rb",
        mode: "100644",
        type: "blob",
        sha: "44b4fc6d56897b048c772eb4087f854f46256132"
      },
      ...
    ]
