Proposal: New method for returning parsed results

[mxgrey]

As it currently stands, a .skel file can return either a Skeleton or a World object. This is somewhat unintuitive, and can probably lead to confusion about which parsing function to call for any given file.

I propose instead returning a struct. Something like this:

struct FileContents
{
  std::vector<WorldPtr> mWorlds;
  std::vector<SkeletonPtr> mSkeletons;
  std::vector<ReferentialSkeletonPtr> mRefSkeletons;
  std::vector<LinkagePtr> mLinkages;
  std::vector<BranchPtr> mBranches;
  std::vector<ChainPtr> mChains;
}

This way everything that a file can possibly contain is obtainable through a single parsing function. It would also address an issue brought up in #378: this would allow ReferentialSkeletons that encapsulate multiple Skeletons to be defined.

I also wonder if we should consider using a file extension besides .skel, since it sort of implies that the file will only contain a single Skeleton, which is not accurate.
