  CHANGE HISTORY:
  
    5 September 2011 -- support for writing Terrasolid's BIN format
    11 June 2011 -- billion point support: p_count & npoints are 64 bit counters
    8 May 2011 -- added an option for variable chunking via chunk()
    9 April 2011 -- added capability to write on-the-fly conversion to ASCII
    24 January 2011 -- introduced LASwriteOpener
    21 January 2011 -- turned into abstract reader to support multiple files
    3 December 2010 -- updated to (somewhat) support LAS format 1.3
    7 September 2008 -- updated to support LAS format 1.2 
    21 February 2007 -- created after eating Sarah's veggies with peanutsauce
