Move examples to root directory

[virtuald]

The only subprojects that have examples are cscore and ntcore, I think.

Should these be moved into an EXAMPLES folder in the project root?

Folder tree would look something like this:

EXAMPLES
|
|
------ cscore
|        --- example1.py
|
|
------ ntcore
|          --- example2.py

[virtuald]

That seems reasonable.
