AST and Anticopypaster plugin for Intellij Idea

This plugin contains a tool, which shows Abstract Syntax Tree of selected code in editor. Tool activation button is located on the toolbar. Also, if user pastes code from clipboard, special message distracts user from work.

• After pressing the "AST" toolbar button ASTAction.actionPerformed is invoked. It constructs ASTRangeTreeNode object, which represents tree root, passes it to com.intellij.ui.treeStructure.Tree constructor and shows final tree in a separate window.
• During the start of a project MessageOnPasteInitializer class is loaded and MessageOnPasteInitializer.initComponent replaces default paste handler with custom MessageOnPaste, which will force a popup message to appear after base class com.intellij.codeInsight.editorActions.PasteHandler processes paste action.
