title: Parsing calculation tree from string
body: <p>I there any built in library in c# or automatic code generator which recieves configuration file and builds parser of calculaton tree from string if there is no could you please help me with advice
  Example:
  "-2+5>3" I would like to build calculation tree where &lt; is root '+' is its right son 3 is left son '-2' is left son of the + and 5 is its right son.
  And the tree could do evaluation in this case true or false.</p>
