> A utility class to convert data from one primitive type to another, in the most commonly used fashions (big endian/little endian byte order, lsb first or msb first).
> It also deals with arrays of primitive types and String containing hexadecimal numbers.
> Such conversions are needed when dealing with embedded software or hardware modeling/design.
> I attach a initial version which deals with the "default" encoding, the one which seems the most natural on the JVM: little endian byte ordering, and, within a byte, lsb first.
> I plan to implement the other encoding I need:
>  - big endian, lsb first
>  - big endian, msb first 
> So far I implemented about half of the methods needed to cover the default encoding:
>  - methods to convert a large data type into an array of a smaller data type (longToBytes for example)
>  - methods to convert an array of a small data type into a larger data type (bytesToLong for example)
> The remaining half consist of the methods to convert from an array of a data type into an array of another data type (bytesToLongs, LongsToBytes)
> Once this is available for different encodings, the most useful part can be done: the "bridge" methods to convert from one encoding to another
