15 // The classes defined here, are utility classes for reading in data
16 // for the FMD. They are put in a seperate library to not polute the
17 // normal libraries. The classes are intended to be used as base
18 // classes for customized class that do some sort of analysis on the
19 // various types of data produced by the FMD.
