	Do not test nodes with static params as it is too difficult
  	to do from the top-level automatically. Indeed, it would
	require to build effective static arg before, which would
	require to make node_check mutually recursive with type_check
	and co. Its not worth the trouble, as such node can be tested
	anyway if used.

LazyCompiler.solve_node_idref:
	compile (with the new function check_static_arg) static
	params instead of ignoring them.

EvalConst.eval_const -> EvalConst.f
	for simplicity and homogeneity with the naming scheme used in EvalType.

Better error msgs.

Renaming idents.

	add a debug rule that hides the mli files and make debugging
	easier w.r.t. var printing.

	 oper -> node
	 func -> extern node
	 node -> (user) node

	turns eq_info into a pair (instead of a struct).

	 CALL_BY_NAME -> STRUCT_n
	 STRUCT_EXP_n -> STRUCT_anonymous_n
	 flaged -> flagged

src/syntaxTreeCore.ml (new file)
	Split      syntaxTree.ml      into     syntaxTree.ml      and
	syntaxTreeCore.ml. The idea is that lic2loc should be able to
	use syntaxTreeCore.ml verbatim.

src/lxm.ml
src/lxm.mli
	remove pack_name from  this module, so that it  can be shared
	with  lic2loc too  (this is  mandatory  since it  is used  by
	SyntaxTreeCore)

	opening SyntaxTreeCore  module, and inline  the definition of
	Lxm.pack_name.

	Also,  begin  to  replace  oper  by node  or  predef_node  in
	identifiers, in order to get a more consistant naming scheme.

   Sligtly generalise  x_check, and  x_check_interface to be  able to
   define      tabulated      version      of     node_check      and
   node_check_interface.  More   precisely,  add  2   fonctions  that
   extracts the name and the package name of a x_key.

   Ditto for lookup_x_eff.

        begin to tranform  the code using V6 compliant  types, but it
        is too much work ().

	Factorize  the code performing  type and  constant references
	solving.

	ident where not authorized to begin by "_"...

src/lxm.ml:
src/global: (new file)
   Add the lustre file name in error messages.

src/compiledData.ml:
   Better Data structure dumping (string_of_type_eff,string_of_const_eff),
   and more dumping (LazyCompiler.check_const_interface).

src/lazyCompiler.ml:
   Fix a bug that prevented enum constants to be exported.
   Indeed, in LazyCompiler.const_check_interface_do, only extern
   constants (Extern_const_eff) were accepted in the provided part, whereas
   enum contants (Enum_const_eff) should also be accepted.

   Force constants interface checking in LazyCompiler.test.

   Some more test files.

	Try to split this 400 lines (!) function.
	+ Factorize some duplicated code.

ParserUtils.flat_flaged_list -> ParserUtils.flat_flagged_list

Ident.t is now an abstract data type (instead of a string).
fullid is turned into an Ident.long, and is also made abstract.

Add basic regression tests.

Add "assert false" statements everywhere it was necessary.

Add the fby operator in the syntax.

Add support for the fby predefined operator
