Example console specification fetcher application
This is a console application that connects to a P4 Server and returns P4 specific information based on user input of 2 words: specification type, specification name. It uses Connection.Login(password) for working with a server at security level 3. Lower security levels should also work and connecting with a user without a password can be done by passing a blank string for password. There is minimal error handling for failed P4 commands. Since -o is used, specifications that do not yet exist may be returned on entry of a non-existent specification name.
