The Script Manager

I have created a Script manager for managing the script command for my UML tool. It is a Singleton as there is only 1 script manager in the application. The responsibility for this manager is to manage the script command enters from input and then digest the command to know what it suppose to do. After that it’ll instruct Paint manager to draw out the diagram. For now this manager is able to accept command from input but it doesn’t know which diagram to be draw on the board as the communication between Script manager and Paint manager haven setup yet.
