//
//  Purpose:	
//  :
//  Chart serializer allows persisting of all chart data and 
//  settings into the stream or file using XML or binary format. 
//  This data can be later loaded back into the chart completely 
//  restoring its state. Serialize can also be used to reset chart 
//  control state to its default values. 
//  Both XML and Binary serialization methods use reflection to 
//  discover class properties which need to be serialized. Only 
//  properties with non-default values are persisted. Full Trust 
//  is required to use chartserialization.
//  SerializeBase class implements all the chart serializer 
//  properties and methods to reset chart content. XmlFormatSerializer 
//  and BinaryFormatSerializer classes derive from the SerializeBase 
//  class and provide saving and loading functionality for XML and 
//  binary format.
//  By default, all chart content is Saved, Loaded or Reset, but 
//  this can be changed using serializer Content, SerializableContent 
//  and NonSerializableContent properties. Content property allows a 
//  simple way to serialize everything, appearance or just chart data. 
//  SerializableContent and NonSerializableContent properties provide 
//  more control over what is beign persisted and they override the 
//  Content property settings. Each of the properties is a string 
//  which is a comma-separated listing of all chart properties to be 
//  serialized. The syntax of this property is "Class.Property[,Class.Property]", 
//  and wildcards may be used (represented by an asterisk). For example, 
//  to serialize all chart BackColor properties set this property to 
//  "*.BackColor".
