NAME: glb_evolve PURPOSE: Computes new globe descriptors at the given time offsets from the given globe descriptors using the taylor series expansion corresponding to the derivatives contained in the given globe descriptor. CATEGORY: NV/LIB/GLB CALLING SEQUENCE: gbdt = glb_evolve(gbd, dt) ARGUMENTS: INPUT: gbd: Array (ngd) of any subclass of GLOBE descriptors. dt: Array (ndt) of time offsets. OUTPUT: NONE KEYWORDS: INPUT: nodv: If set, velocities will not be evolved. copy: If set, the evolved descriptor is copied into the input descriptor and it is freed. The input descriptor is returned. OUTPUT: NONE RETURN: Array (ngd,ndt) of newly allocated globe descriptors evolved by time dt, where ngd is the number of gbd, and ndt is the number of dt.
