Memory Leak

When training the eigenface recognizer multiple times resources will not be 
freed.
1. train the eigenface recognizer
2. add training images
3. train the same eigenface recognizer again, by calling train on it

It is expected to work, but previously allocated resources are not freed. This 
issue might be fixed by migrating to the C++ interface for PCA, or rewriting 
the free memory method.

After closing the program, 1 thread remains running. (most likely the main thread)

What steps will reproduce the problem?
1. Run the program in debug mode
2. Close the program, and the debugger will stay active

The program runs 7 threads: 1 main thread, 2 boost::threads and 4 opencv 
threads. When the program stops look at the ID's of the threads and you will 
see that only the main thread hasn't exited.

Link errors come when you rebuild the project

What steps will reproduce the problem?
1. download and extract the visual control zip file
2. add/remove the required c++ files in the solution (matching to the physical 
file structure)
3. Setup all include and lib paths
4. Just BUILD, then it works
5. Now just REBUILD

What is the expected output? What do you see instead?
It should be possible to run without any errors
But now it gives me lot of link errors

Add threshold to enable the recognition process to designate a face as unknown too

1. train the recognizer
2. recognize an unknown face
3. it will always give one of the training images back, the closest one

desired result: designate face as unknown when the test image is not a close 
enough match

"The recognizer has indicated that it did not train correctly"

What steps will reproduce the problem?
1. download and extract the visual control zip file
2. capture faces and store them as training images
3. press "Train Recognizer" and recieve "The recognizer has indicated that it 
did not train correctly" error pop-up message

Necessitate others library on Windows8

The binary needs two dynamic libraries, msvcp100.dll and msvcr100.dll on 
Windows8 x64, but I presume x86 also.
