\fn ZRef<ZAssetTree> ZUtil_Asset::sGetAssetTreeFromFileSpec(const ZFileSpec&)
\brief Return a new ZAssetTree instance referencing the zao data in the
file referenced by \a iFileSpec.
It is important to recognize that each invocation of this method creates
a \em new instance of ZAssetTree. It may therefore load or map all the data contained in
the tree. Your application will probably call this method indirectly by calling
ZUtil_Asset::sGetAssetRootFromFileSpec, but it should do so only once, keeping the asset
in a global static or in an instance variable of your application object (or equivalent).
