Removed all references to #ifdef SWIGJAVA and JAVACALLBACK from the
library source. All java-specific source code has been moved to the
corresponding library's .i file for java.
* Update library source
* Update examples where necessary
* The function pointer methodology has been remove from libraries
which provided callbacks as both a class and a function pointer
implementation. Examples were updated to use the class version
of callbacks.
* Updated documentation for SWIGJAVA
