Changes to 0.4 (includes all changes from all >0.3.1)

* new syntax for writing functions, more math like
* functions are now passed by value not by reference, this is unfortunately
  backwards incompatible but adds consistency and flexibility, so just instead
  of sum(4,5,&func) you'd write sum(4,5,func), with anonymous functions,
  the calling syntax does not change. inside the function then, one would use
  func(...) instead of *func(...)
* library file is compiled now for quick startup
* many new functions
* more matrix support
* complete complex number support with new operators

Changes to 0.3 (includes all changes from all >0.2.1)
