Full inferno support!
Just use these import paths for a component that's fully compatible with Inferno:
import Map from 'pigeon-maps/inferno'
import Marker from 'pigeon-marker/inferno'
import Overlay from 'pigeon-overlay/inferno'
Thank you @degroote22 for bringing this up and all your contributions!
Thank you @trueadm for making Inferno and all your help in getting this working!
