commandmanager.h

// CommandManager handles the operations of looping through the command
// data file. Interface between library object, command object, and data
// file.
//
// Assumptions:
//  -- data file will be correctly formatted
//  -- data file will contain no empty lines
//
// Implementation:
//  -- reaching eof character breaks the for loop
//  -- prints error messages on invalid input from file
