Include exception handling in get() add session.close()
Include exception handling in get() add session.close()

Added in an exception handler that tries to do the sqlalchemy command and if it can't, then it rollsback and returns an error message
Also added a session.close at the bottom
Possible need to add error handling to the lazyload of the other table objects later on just incase they don't exist for a particular employee.
