public class Parser
extends java.lang.Object

Very simple Parser that reads a "lisp"-expressions and parses it to an abstract syntax tree. The AST is not represented as an intermediary data type but as closely to Java data types as possible. This is done to allow smooth integration of Lisp and Java code.
