+Assuming previously defined Attribute, compiled in a vector known as 'vec' and with subsequent numbers added
+
+To create a table:
+
+	engine.createTable("table1", vec);
+
+
+This creates a Relation object with the appropriate Attribute objects. It displays nothing.
+
+To display the table:
+
+	engine.showTables(engine.getTableFromName("table1"));
+
+
+This results in such output:
+
+	Display of relation--------------------------------
+	Relation name: table1
+
+	Attribute name: name
+	Elements: Fry      Bender      Leela      Zoidberg
+	Attribute name: age
+	Elements: 22      5      22      50      
+
+
+With table3 having an equal domain to table1, this:
+
+	cout << engine.unionComp(engine.getTableFromName("table1"), engine.getTableFromName("table3"));
+
+
+This will display:
+
+	1
+
+
+To project a table's column:
+	
+	engine.project((engine.getTableFromName("table1")), "name");
+
+
+This will display:
+
+	-----------Initiated Query Projection---------
+	Column Title: name
+	Fry
+	Bender
+	Leela
+	Zoidberg
+
+
+With an arbitrary vector of strings as cmds (until we are able to parse effectively):
+
+	engine.saveToFile(cmds);
+
+
+This will result in a db file with the contents:
+
+	CREATE TABLE animals (name VARCHAR(20), kind VARCHAR(8), years INTEGER) PRIMARY KEY (name, kind);
+	
+SHOW animals;
+
+
+
+//insert
+
+//delete
+
+//select
+
+//product
