fixing levels in harvard elevator above main area

Added ramps connecting subway platforms to the main indoor area. Mapping still rough in position. Modified landing between ground and main area to be level -0.5 as it is above the rail lines. Added layers

Adding large area before turnstiles in harvard T stop at level -1.5. This is a rough mapping based on known connections

Changed path to steps, connected turnstiles

Added paths, escalator, stairs as paths, turnstiles to the harvard T stop next to the subway platforms. I used level -0.5 for the turnstile area, -1 for the outbound platform, -2 for the inbound. The layers don't match up exactly

Expanded local areas inside the harvard T stop. Corridors for the stairwells, and the bridge above both subway platforms
