Robert Griesemer 5ee7ef90cd suffixarray: improved serialization code 
Use gobs to serialize indexes instead of encoding/binary.

Even with gobs, serialize data in slices instead of
applying gob to the entire data structure at once,
to reduce the amount of extra buffer memory needed
inside gob.

7x faster Write/Read for new BenchmarkSaveRestore
compared to old code; possibly because encoding/binary
is more expensive for int32 slice elements (interface
call to get little/big endian encoding), while gob's
encoding is fixed (unconfirmed).

new (using gobs):
suffixarray.BenchmarkSaveRestore	       1	2153604000 ns/op

old (using encoding/binary):
suffixarray.BenchmarkSaveRestore	       1	15118322000 ns/op

The actual serialized data is slightly larger then using
the old code for very large indices because full 32bit indices
require 5bytes using gobs instead of 4bytes (encoding/binary)
in serialized form.

README 

This is the source code repository for the Go programming language.  

For documentation about how to install and use Go,
visit http://golang.org/ or load doc/install.html in your web browser.

After installing Go, you can view a nicely formatted
doc/install.html by running godoc --http=:6060
and then visiting http://localhost:6060/doc/install.html.

Unless otherwise noted, the Go source files are distributed
under the BSD-style license found in the LICENSE file.

Binary Distribution Notes

If you have just untarred a binary Go distribution, you need to set
the environment variable $GOROOT to the full path of the go
directory (the one containing this README).  You can omit the
variable if you unpack it into /usr/local/go, or if you rebuild
from sources by running all.bash (see doc/install.html).
You should also add the Go binary directory $GOROOT/bin
to your shell's path.

For example, if you extracted the tar file into $HOME/go, you might
put the following in your .profile:

    export GOROOT=$HOME/go
    export PATH=$PATH:$GOROOT/bin

See doc/install.html for more details.
