Too much is imported by basic imports

[rob-smallshire]

If I perform a basic import such as,

from constituent_treelib import ConstituentTree, Language

many package which I don't need are imported. This is problematic for Python environments where tkinter is not available, such as when the Python interpreter is provisioned by pyenv or by uv, as is increasingly common. In fact, the above import fails in such environments with,

    from constituent_treelib import ConstituentTree, Language
/Users/rjs/.virtualenvs/demonstrable-codex/lib/python3.11/site-packages/constituent_treelib/__init__.py:3: in <module>
    from constituent_treelib.core import *
/Users/rjs/.virtualenvs/demonstrable-codex/lib/python3.11/site-packages/constituent_treelib/core.py:17: in <module>
    from .export import export_figure
/Users/rjs/.virtualenvs/demonstrable-codex/lib/python3.11/site-packages/constituent_treelib/export.py:8: in <module>
    from nltk.draw.tree import TreeView
/Users/rjs/.virtualenvs/demonstrable-codex/lib/python3.11/site-packages/nltk/draw/tree.py:12: in <module>
    from tkinter import IntVar, Menu, Tk
/Users/rjs/.pyenv/versions/3.11.4/lib/python3.11/tkinter/__init__.py:38: in <module>
    import _tkinter # If this fails your Python may not be configured for Tk
E   ModuleNotFoundError: No module named '_tkinter'

I solved this, by modifying my installation of Constituent-TreeLib by removing from .export import export_figure from core.py. Now my program works, and I can use your otherwise excellent library successfully.

Please consider making default imports less onerous. We can import the visualisation code if we need it.
