Parser Component parses and evaluates mathematical expressions given as strings at runtime. The expression can contain predefined or user defined variables and functions. When evaluation is requested, the parser compiles the expression into a parse tree. Further evaluations are made using this tree that represents the expression. The parser can optimize the tree by simplifying branches that evaluate to a constant.

An example expression is : LN(X)+SIN(10/2-5)
When parsed, this expression will be represented as:
<LN(X)+0>
since the SIN(10/2-5) is in fact SIN(0) which is a constant and is 0. Source code is included.
