## 0.34 (2016/05/10)
  NB: changes prefixed with "==>" belows breaks existing code!
  NB: changes prefixed with "-->" belows makes existing code deprecated
  * ==> new syntax:
       X<<Y for X is before Y in the linear order
       X<Y fot X is immediatly before Y in the linear order (diff from semantics introduced in 0.32)
  * ==> new_syntax for regular expression on label edges:
      NEW: X -[re"__your_regular_expression_here__"]-> Y
      OLD: X -[aux:*]-> Y is not supported anymore
  * ==> new_syntax for regular expression on featues:
      NEW: X.feat = re"__your_regular_expression_here__" (no whitespace between re and double quote)
      OLD: X.feat == "__your_regular_expression_here__" introduced in 0.32 is not supported anymore
  * --> remove lex_rule keyword: use "rule" instead
  * --> add_neighbour is now deprecated and new syntax is introduced for nodes creation:
      add_node X        Create a new node named X wihtout position constraint
      add_node X :> Y   Create a new node named X immediatly after Y
      add_node X :< Y   Create a new node named X immediatly before Y
  * improve search for a sequence:
      1) search for the sequence with the requested name
      2) search for the module with the requested name
      3) select the first sequence defined in the GRS file
  * domain can be declared in a external file
  * add functions Rewrite.set_max_depth_non_det and Rewrite.set_max_depth_det to the library

    - improve checking for consistency between rules and feature domain at GRS loading time
    - add the possibility to use parameters in the without part
