Bantam Java Compiler Project -- Version 1.3

  Changes from 1.2:
    * Added JVM target for generating Java Virtual Machine Code,
      which can be converted by Jasmin into class files
    * Added an optimizer component for optimizing programs
      (the opt/ and cfg/ packages contain this code)
    * Added an interpreter component for interpreting programs
    * String.equals now takes an Object as a parameter
      (as it does in Java)
    * Added Object.toString, Object.equals, Sys.time, and 
      Sys.random built-in methods
    * Symbol table is no longer flushed after semantic analysis
      and can be used by code generator
    * Fixed other minor bugs in solution, API, and manual

  Changes from 1.1:
    * Made String.equals parameter type Object rather than String to
      conform with Java's definition of String.equals
    * Added an extended language (includes arrays, for loops, etc.)
    * Fully implemented lexer in JavaCC version of reference compiler
      (lexical errors caught in lexer rather than in parser -- thanks
       to David Furcy for identifying this and providing solution code)
    * Fixed off by one conformance testing bug in reference compiler
    * Fixed difference in language between Bantam Java and Java:
      Bantam Java now does not allow redeclaration of local variables
      with overlapping scopes
    * Fixed other minor bugs in solution, API, and manual
