    Cristina Moraru authored
    This commit adds the feature of querying the drive for the
    Recommended Access Order (RAO) of a series of files and adds
    a test file for this feature.
    Changes of this commit:
      *  Extend the DriveInterface with a virtual method queryRAO
    which takes as parameter the name of the file containing a set
    of files for which the RAO is requested. The line format of this
    file is the following:
      *  Extend DriveGeneric class with the implementation of the
    method queryRAO, along with a few other auxiliary methods; some
    key auxiliary methods are getLimitUDS, generateRAO, receiveRAO
      *  Add method queryRAO in object FakeDrive returning Exception:
    Not Implemented
      *  Add auxiliary constants and structures in a new 'RAO' namespace
      *  Add test file: BasicReadWriteTest.cpp which can perform 3 tests
    according to the setting of variable 'test'
    	1. BLOCK_TEST - basic read / write of blocks
    	2. FILE_TEST - writes a series of CASTOR files and reads
    a random one
    	3. RAO_TEST - performs a RAO query for a series of files
    given in the filename specified in argv[1]. The file format should
    respect the above mentioned order.
