+% Parse a string with alignement definitions and separate

+% \@easy@list@align muist contains the possible alignments.

+% @ => no rule
+% . => dotted rule
+% ; => dot-dash rule
+% : => dased rule
+% | => solid rule
+% 0123456789 => solid rule 0 => thin 9 => thick
+% 
+% The output are
+% \@easy@align: which will contain alignement string
+% \@easy@rules: which will contain rule definition string
+% 
+% for example
+% \def\@easy@list@align{rcl}
+% \@easy@list@align{|r;cl}
+% results in
+% \@easy@align => rcl
