fc/fcsend.m: add return of excitation data
fc/fcsweep.m: add prints to help user follow steps during execution of fast commands; allow profiles matrices to have arbitrary number of profiles; replace sinus by cosinus as sinusoidal function for allowing 0 Hz (DC) excitation
fa/faload.m: allow memory preallocation for returned data
fa/fasave.m: complete implementation of ASCII save
fa/faspec.m: fix bugs
fa/faspecgram.m: fix bugs
fa/fatimelvrt2m.m: better implementation based on differences between consecutive items of the timestamp array
modelid/idcorrps.m: absorb poles at 0 as LTI models time delay
fa/facutdata: add function to cut FA data at desired indices
ofbsim/: use identified orbit corrector models in simulation
fa/*: small modifications to deal with date and time; now faplot is shown in seconds + start time
