    Creates a directory and file tree based on a dictionary structure.

    Each key in the dictionary represents a file or directory name.
    If the value is a dictionary, it represents a subdirectory with its own structure.
    If the value is a string, the key is taken to represent a file with this value as its content.

    Parameters
    ----------
    directory : pathlib.Path
        The root directory where the tree will be created.
    structure : dict
        A nested dictionary representing the directory and file structure.
