"Added new test 'Complex' and improved error debugging"

This revision adds a complex test to the 'TestInterpreter.cpp' file to test functionalities such as classes, variable initializations, loops, conditionals and methods in the interpreter. The token parser has also been updated with a reset method in the 'parser.cpp' file for cleaning up any previous state before parsing a new script. This ensures the parser starts fresh for each new parse request. It also improves the debugging process in 'function.cpp' by printing the description of parser errors. Few completed tasks are removed from the TODO list.
