//  MBadPixelsMerge
//  ===============
//
//  Merges in ReInit two bad pixel containers together:
//   1) The contents of the container given in the constructor is in ReInit
//      merged into MBadPixelsCam from the parameter list (aka run-headers)
//   2) MBadPixelsCam from the parameter list (aka run-headers) is merged
//      into the container given in the constructor. While the contents
//      to which 1) refers are still untouched.
//
//
// An explanation taken from Mantis:
// --------------------------------
// In my eyes everything works a supposed to do. We have different sources
// for bad-pixels, eg from Pedestal calculation, from the calibration
// constant calculation, manual setting and so on. If processing data we
// have to take care of all this different sources. Therefor we have to
// store the bad pixels from this sources (eg. from calibration). In
// addition MBadPixelsCam is read from the file containing the data (once
// per file). Now always after a new (data-)file has been opened the bad
// pixels from (for example) the calibration file have to be merged into
// the container loaded from the (data-)file which is stored in the
// parameter list. Copying the pointer would totally overwrite the pixels
// loaded (automatically by MReadMarsFile) from the data-file. All this is
// done using a copy of the original MBadPixelsCam (fSource). In addition
// fDest is initialized to the pointer given as argument to the
// constructor. To keep track of all bad pixels the instance this pointer
// is pointing to is used to collect all bad pixels used so far.
//
//
//  Input Containers:
//   MBadPixelsCam

//  Output Containers:
//   MBadPixelsCam
