7// class AliRunLoader //
8// //
9// This class aims to be the only one interface for manging data //
10// It stores Loaders for all modules which knows the filenames //
11// of the data files to be stored. //
12// It aims to substitude AliRun in automatic managing of data //
13// positioning thus there won't be necessity of loading gAlice //
14// from file in order to get fast access to the data //
15// //
16// Logical place to put the specific Loader to the given //
17// detector is detector itself (i.e ITSLoader in ITS). //
18// But, to load detector object one need to load gAlice, and //
19// by the way all other detectors with their geometrieces and //
20// so on. So, if one need to open TPC clusters there is no //
21// principal nedd to read everything. //
