-// This abstraction layer is for use with file formats that have 64-bit/32-bit and Big-Endian/Little-Endian variants
-//
-// For example: to make a utility that handles 32-bit little enidan files use:  Pointer32<LittleEndian>
-//
-//
-//		get16()			read a 16-bit number from an E endian struct
-//		set16()			write a 16-bit number to an E endian struct
-//		get32()			read a 32-bit number from an E endian struct
-//		set32()			write a 32-bit number to an E endian struct
-//		get64()			read a 64-bit number from an E endian struct
-//		set64()			write a 64-bit number to an E endian struct
-//
-//		getBits()		read a bit field from an E endian struct (bitCount=number of bits in field, firstBit=bit index of field)
-//		setBits()		write a bit field to an E endian struct (bitCount=number of bits in field, firstBit=bit index of field)
-//
-//		getBitsRaw()	read a bit field from a struct with native endianness
-//		setBitsRaw()	write a bit field from a struct with native endianness
