+  LZ packer/unpacker

+  Code is mostly from lzhuf.c found at

+***********Original Comment***********************************************
+    lzhuf.c
+    written by Haruyasu Yoshizaki 1988/11/20
+    some minor changes 1989/04/06
+    comments translated by Haruhiko Okumura 1989/04/07
+    getbit and getbyte modified 1990/03/23 by Paul Edwards
+      so that they would work on machines where integers are
+      not necessarily 16 bits (although ANSI guarantees a
+      minimum of 16).  This program has compiled and run with
+      no errors under Turbo C 2.0, Power C, and SAS/C 4.5
+      (running on an IBM mainframe under MVS/XA 2.2).  Could
+      people please use YYYY/MM/DD date format so that everyone
+      in the world can know what format the date is in?
+    external storage of filesize changed 1990/04/18 by Paul Edwards to
+      Intel's "little endian" rather than a machine-dependant style so
+      that files produced on one machine with lzhuf can be decoded on
+      any other.  "little endian" style was chosen since lzhuf
+      originated on PC's, and therefore they should dictate the
+      standard.
+    initialization of something predicting spaces changed 1990/04/22 by
+      Paul Edwards so that when the compressed file is taken somewhere
+      else, it will decode properly, without changing ascii spaces to
+      ebcdic spaces.  This was done by changing the ' ' (space literal)
+      to 0x20 (which is the far most likely character to occur, if you
+      don't know what environment it will be running on.
