PROCEDURE: MVN_EPH_RESAMPLE PURPOSE: Samples MAVEN ephemeris data at times specified by user. Uses spline interpolation. USAGE: mvn_eph_resample, time, eph_in, eph_out INPUTS: time: An array of times at which ephemeris data are desired. Can be in any format accepted by time_double(). eph_in: An MAVEN ephemeris structure obtained from 'get_mvn_eph'. These data should have at least some overlap with the input time array (obviously). *** This routine WILL NOT extrapolate. *** eph_out: The ephemeris data sampled at the input times.

This procedure is based on the MGS routine written by David L. Mitchell. The original routine name is 'mgs_eph_resample' (created on 2003-01-28, and the last version is 1.1 on 2011-03-06). 2014-11-25: Minor revision and header description is written.
