docs: Get the number of additional burn-in runs that will be performed for the search with the given ID.
  If no specific number of burn-in runs has been set for this search using {@link #setNumBurnIn(String, int)},
  the global value obtained from {@link #getNumBurnIn()} is returned. Burn-in runs are executed before the
  actual search runs and not registered in the results, to "warm up" the analysis in order to reduce the
  influence of just in time compilation (JIT) and on the fly optimizations performed by the JVM.
  
  @param searchID ID of the search
  @return number of additional burn-in runs that will be performed for this search
  @throws UnknownIDException if no search with this ID has been added
