class AliTreeLoader

Container of all data needed for full
description of each data type
(Hits, Kine, ...)

Each data loader has a basic standard setup of BaseLoaders
which can be identuified by indexes (defined by EStdBasicLoaders)
Data managed by these standard base loaders has fixed naming convention
e.g. - tree with hits is always named TreeH
(defined in AliLoader::fgkDefaultHitsContainerName)
- task DtectorName+Name defined

EStdBasicLoaders   idx     Object Type        Description
kData           0    TTree or TObject     main data itself (hits,digits,...)
kTask           1        TTask            object producing main data
kQA             2        TTree                quality assurance tree
kQATask         3        TTask            task producing QA object


User can define and add more basic loaders even Run Time.
Caution: in order to save information about added base loader
user must rewrite Run Loader to galice.file, overwriting old setup
