Construct fChain, also adding friends if needed and injecting knowledge of offsets if available.

Parameters

[in]	treeNames	Name of the tree for each file in fileNames.
[in]	fileNames	Files to be opened.
[in]	friendInfo	Information about TTree friends, if any.
[in]	nEntries	Number of entries to be processed.
