Tests if a particular fractional coord is within a fractional coord_list.

    Args:
        fcoord_list: List of fractional coords to test
        fcoord: A specific fractional coord to test.
        atol: Absolute tolerance. Defaults to 1e-8.

    Returns:
        True if coord is in the coord list.
