C{Lazy import} is I{supported only for U{Python 3.7+ <https://Snarky.CA/lazy-importing-in-python-3-7>}} and is I{enabled by default in U{PyGeodesy 18.11.10+<https://PyPI.org/project/PyGeodesy>} and later}. To I{enable} C{lazy import}, set C{env} variable C{PYGEODESY_LAZY_IMPORT} to C{1}, C{2}, C{3} or higher prior to C{import pygeodesy}. To I{disable} C{lazy import}, set C{env} variable C{PYGEODESY_LAZY_IMPORT} to C{0} or an empty string. Use C{2} or higher to print a message for each lazily imported module and attribute, similar to C{env} variable C{PYTHONVERBOSE} showing imports. Using C{3} or higher also shows the importing file name and line number. @note: C{Lazy import} applies only to top-level modules of C{pygeodesy}.
