Re-written API configuration method

Completely re-written the method with which a new developer can configure and set up its coding environment for the NERDZ platform.

Some files need to be deleted or corrected (e.g., we will delete the *testAll.sh* which is not necessary anymore and we need to update the initdb.sh file for the database).

There is a little error that we need to correct and it's the definition of the function *WinDBCommand()* which seems not recognized! We will work it.
This value shouldn't be a constant value. Line 15 and 16 should be moved to line 5 and 6. So the user understand that these values are variable values and can change it according to his configuration
