* added intellij ide gitignore
* IE9 and IE10 require loose to work
your demo app doesn't work on IE9/10 so you will need to make a more simple one to test this fix out. the issue is to do with this.props not being avaiable in constructors for IE9/10 see: https://github.com/babel/babel/issues/3975 it was supposidly fixed 1 year ago but I can't see it working, maybe we need to swap to @babel/core to get this fix? I tried it but the change is made larger due to the curent demo apps build system.
Full fix would involve upgading to @babel/core + @babel/preset-env and migrating away from kotatsu in favour of a plain ole react app via webpack (create-react-app maybe?) and then place it into another folder and have that folder habing it's own package.json so we can consume google-map-react as if it were a real library during testing. Sure we would loose hmr, but at this stage hmr isn't all that useful anyway.
I'de love the proper fix, but for now I have clients with IE10 browser requirements.
