/**
* Thrown to indicate that a block of code has not been implemented.
* This exception supplements UnsupportedOperationException
* by providing a more semantically rich description of the problem.
*
* NotImplementedException represents the case where the
* author has yet to implement the logic at this point in the program.
* This can act as an exception based TODO tag.
* Because this logic might be within a catch block, this exception
* suports exception chaining.
