lazy_loader is copied to Ext now, modified external imports to lazy_load add a few more imports to be lazy loaded, think the install path is correct now [TD]"<" symbol embedded in html revert changes to path modules for testing use lazyloader in PathAreaOp.py add back in deferred loading temp change to print error message in tests temp change to print error message in tests add _init__.py to lazy_loader make install in CMakeLists.txt one line
