command.cpp

// Parent class to child command classes
// Handles the commands from the file. Manages subclasses using input command
// characters. Builds command objects from data file and calls execute.
//
// Assumptions:
// -- Data file format is correct
//
// Implementation:
// -- Has access to Library class through a reference to a pointer
// -- Builds and checks command type and values
//
