Branch: MAIN +
+Rewrited NeL, NeLNS, and Snowballs configure.in scripts.
+ADDED an 'acinclude.m4' file which contain all M4 macros to check paths of the libraries that we need and macros to check the intalation of NeL. This file is placed in the code directory and there is symbolic links to that file in the 'nel', 'nelns' and 'snowballs2' directories.
