Add directions search component

[marleymarl]

See attached. This is a component that should fit within the width of the 'data' column within MapContainer.js. For now simply mock a function on submit to geocode the places/addresses entered (to and from) and log them to console. When there is a back-end API available for this, the function should post this data to the API and get back directions to display but the processing and display should be a separate issue.
