/*RunCollector.h
 *Class that searches through a directory looking for files of a specified format.
 *Stores all filenames in a vector which can be accessed by other functions/classes for
 *further use. Can also use Merge() to combine all files using hadd into a single file.
 *Merge() is NOT RECOMMENDED in the analyzer program.
