<hr><a name="_details"></a><h2>Detailed Description</h2>
This class is used to access data which stored in big endian order regardless of the conventions of the platform.
<p>
It has been designed to automatically detect the endian-ness of the platform, so that a compilation flag is not needed.<p>
All methods are static and inline in an attempt to induce the compiler to do most of the calculations at compile time.<p>

This method detects the endian-ness of the platform by casting a pointer to a word to a pointer to a byte.

On big endian platforms the FF will be in the byte with the lowest address. On little endian platforms, the FF will be in the byte with the highest address.<p>
