Attached patch + new file make FGNavRecord have a .cxx file, and a constructor w hich allows all the parameters to be supplied. Along the way I also cleaned up t he navrecord.hxx header, lots more header pollution has been killed. Some long methods are no longer inline, but were all suspiciously long to meet c ompiler inlining criteria (I'm not clear if the 'inline' keyword is advisory or mandatory in this situation) - I don't expect this to affect performance in any way whatsoever. The constructor addition is to support some hacking I'm doing improving the star tup performance of the navDB by lazily loading the data, and caching it in a mor e efficient format than text. I'm submitting this change (and probably some othe r small tweaks in the future) since they are worthwhile as cleanups regardless o f how my current experiments work out.
