19 | @brief FMD utility classes for reading FMD data | |
20 | */ | |
a1f80595 | 21 | //___________________________________________________________________ |
22 | // | |
23 | // The classes defined here, are utility classes for reading in data | |
24 | // for the FMD. They are put in a seperate library to not polute the | |
25 | // normal libraries. The classes are intended to be used as base | |
26 | // classes for customized class that do some sort of analysis on the | |
27 | // various types of data produced by the FMD. | |
