// Analysis
//
// This is the top-level analysis class used to hide the (little) differences between TAM standalone
// and TAM with PROOF.  In addition it provides an almost transparent interface in the case you want
// to do mixing of different events.
// 
// The class can operate in following modes:
//  a) Add single files to be analyzed using Analysis::AddFile
//  b) Use a text file to point to files to be analyzed using Analysis::AddFiles
//  c) Add files using a catalog using Analysis::AddDataset
//  d) Use of environment variables (only will be attempted if none of a-c is provided)
//     MIT_CATALOG  (eg. export MIT_CATALOG=/home/mitprod/catalog)
//     MIT_BOOK     (eg. export MIT_BOOK=mit/filler/006)
//     MIT_DATASET  (eg. export MIT_DATASET=s8-ttbar-id9)
//     MIT_FILESETS (eg. export MIT_FILESETS=0000;0001;0002)
//   or   
//     MIT_FILES    (eg. export MIT_FILES=file1;file2;file3)
//
// See $CMSSW_BASE/src/MitAna/macros/examples/runSimpleExample.C
// for an example of how to use this class.
