18// Class for Parsing simple text configuration files //
19// It produces a TMap for the Key=>Value pairs found in the //
20// Configutation file. //
21// //
22// The configuration file has a simple structure: //
23// * Lines starting with a # or empty lines are ignored //
24// * Key and Value are separated either by a <tab> or <space>es //
25// //
26// Currently the class is used in the TPC DAs to allow an adjustment of //
27// the most relevant parameters without recompiling the DAs //
