+This is a user based Button manager, this adds support for
+	* dynamic GUIs that can be moved around on screen (not dragable)
+	* alternating text
+	* buttons that expire after certain amount of time
+To use:
+	* on NCN:
+		* You will need to have a variable in your plugin class that stores ButtonHandlers
+			* create new button Manger:
+				* $this->BTNMan[$NCN->UName] = new betterButtonManager($UCID);
+		* create a timer like so: 
+			$this->createNamedTimer("PluginName_ButtonHandle_{$NCN->UName}", 'DoButtonHandle', 0.50, Timer::REPEAT, array($NCN->UName));
+			* The function for this timer is:
+					public function DoButtonHandle($UName)
+					{
+						$this->BTNMan[$UName]->HandleButtons();
+					}
+	* To create a new button:
+		* $this->BTNMan[$UName]->InitButton(ButtonName, Group, Top, Left, Width, Height, ButtonStyle, Text, SecondsToShow);
+			* example: $this->BTNMan[$UName]->InitButton('Welcome', 'welcomescreen', 50, 50, 100, 100, ISB_DARK, 'Welcome to Our Server!', 10);
+			This will create a button that is:
+				* 50 down from the top
+				* 50 from the left
+				* 100 wide
+				* 100 tall
+				* Dark Background
+				* Welcomes the user,
+				* Stays on screen for 10 seconds
+	* To load a cluster:
+		* $this->BTNMan[$UName]->LoadGUICluster('example_cluster', 'example_layout', 100, 100);
+			* this will load the ini file /plugins/gui/example_cluster/example_layout.ini
+	* To remove a single button:
+		* $this->BTNMan[$UName]->RemoveButton('Welcome');
+	* To remove a button group/cluster
+		* $this->BTNMan[$UName]->RemoveGroup('welcomescreen'); #this will remove the button we used
+		* $this->BTNMan[$UName]->RemoveGroup('example_cluster'); #this will remove the cluster we used
+	* To move a cluster
+		* you have 3 options
+			* move just vertically
+				* $this->BTNMan[$UName]->MoveGUIClusterV('example_cluster', 5)
+					* Will move the cluster down 5
+			* move just horizontally
+				* $this->BTNMan[$UName]->MoveGUIClusterH('example_cluster', 10)
+					* Will move the cluster right 10
+			* or move both vertical and horizontal
+				* $this->BTNMan[$UName]->MoveGUIClusterD('example_cluster', 5, 10)
+					* Will move the cluster down 5, and right 10
+	* SIDE NOTE: each cluster will only show 1 layout at a time
+		* For example if you do
+			* $this->BTNMan[$UName]->LoadGUICluster('example_cluster', 'example_layout', 100, 100);
+		* then do
+			* $this->BTNMan[$UName]->LoadGUICluster('example_cluster', 'example_layout2', 100, 100);
+		* the call to load the 2nd layout will remove all buttons from the example_cluster that is shown
+			and then show the new layout
