A company is trying to find out if a meeting room is available for a new meeting. The meeting room can only hold one meeting at a time. Write a function that determines if a new meeting can be scheduled in the meeting room given the existing meeting times.

The function should accept an array of existing meetings (each represented as a tuple [start, end] where start and end are the start and end times of the meetings) and a new meeting time (also represented as a tuple/array [start, end]). The function should return true if the new meeting can be scheduled without overlapping any of the existing meetings, and false otherwise.
