declarative way to read and write binary file formats
BinData is a declarative way to read and write binary file formats.
This means the programmer specifies *what* the format of the binary data is, and BinData works out *how* to read and write data in this format. It is an easier ( and more readable ) alternative to ruby's #pack and #unpack methods.
