[Insight-developers] configure has moved

[Bill Hoffman]

I have moved the autoconf configure script to the top level Insight directory.
This is to allow builds in different directories.  If you are building on
unix, you will have to re-run configure from the top level directory.

You can also build in separate directories now.  

For example, this should build the Insight code in a directory
called Insight-linux:

cvs checkout Insight
mkdir Insight-linux
cd Insight-linux
../Insight/configure
make

(Note, if you try this, use a clean checkout, once it has
been configured for in-place builds, it does not switch 
to remote builds)

Of course, you can still build in-place, but you now
have to run configure from the Insight directory and
not Insight/Code.
