WHAT'S NEW IN UT2003.2.4

#1. ut2003.2.4 Undertow Suite will now read  data coming from the simulator in interactive mode even with very small additions to the data in the waveform file.
                                                                                                                            
#2. Added support for the split/spo format
                                                                                                                            
#3. Added in speed ups for the Veritools' API when this file is writing data across a network from a Linux system.
                                                                                                                            
    1. Added compression in memory to fast file API.
                                                                                                                            
    2. Added environment variable that can be used to set the size in
megabytes of the compression chunks in the fast file API,
VT_COMPRESS_CHUNK_SIZE_MB.  Default is 16.
                                                                                                                            
    3. Added environment variable that can be used to set the maximum
size in memory of the data buffer per signal in bytes,
VT_MAX_BUFFER_PER_SIGNAL.  Default is 4096.
                                                                                                                            
    4. Changed default compression level for fast file API from
0 (no compression) to 3 (maximum high speed compression).
