//////////////// CAUTION !!!! STOP !!! Read this before you proceed !!!!!!! /////////////
/// 1. This Class handles Configuration Parameters of AAMP Player , only Config related functionality to be added
/// 2. Simple Steps to add a new configuration
///		a) Identify new configuration takes what value ( bool / int  / string )
/// 	b) Add the new configuration string in README.txt with appropriate comment
///		c) Add a enum value for new config in AAMPConfigSettingInt, AAMPConfigSettingBool, AAMPConfigSettingFloat, or AAMPConfigSettingString.
/// 	d) Add the config string added in README and its equivalent enum value in corresponding
/// 		mConfigLookupTableInt, mConfigLookupTableBool, mConfigLookupTableFloat, or mConfigLookupTableString
/// 	e) Go to AampConfig constructor explicitly initialize of different value than default is required (int: 0, bool:false, float:0.0, string:"")
/// 	f) Thats it !! You added a new configuration . Use Set and Get function to
///			store and read value using enum config
/// 	g) IF any conversion required only (from config to usage, ex: sec to millisec ),
///			add specific Get function for each config
///			Not recommended . Better to have the conversion ( enum to string , sec to millisec etc ) where its consumed .
