Remarks
A float buffer.
This class defines four categories of operations upon float buffers:
<ul>
<li>
Absolute and relative #get() <i>get</i> and #put(float) <i>put</i> methods that read and write single floats;
</li>
<li>
Relative #get(float[]) <i>bulk get</i> methods that transfer contiguous sequences of floats from this buffer into an array; and
</li>
<li>
Relative #put(float[]) <i>bulk put</i> methods that transfer contiguous sequences of floats from a float array or some other float buffer into this buffer; and
</li>
<li>
Methods for #compact compacting, #duplicate duplicating, and #slice slicing a float buffer.
</li>
</ul>
Float buffers can be created either by #allocate <i>allocation</i>, which allocates space for the buffer's
content, by #wrap(float[]) <i>wrapping</i> an existing float array into a buffer, or by creating a <i>view</i> of an existing byte buffer.
Like a byte buffer, a float buffer is either <i>direct</i> or <i>non-direct</i>. A float buffer created via the wrap methods of this class will be non-direct. A float buffer created as a view of a byte buffer will be direct if, and only if, the byte buffer itself is direct. Whether or not a float buffer is direct may be determined by invoking the #isDirect isDirect method.
Methods in this class that do not otherwise have a value to return are specified to return the buffer upon which they are invoked. This allows method invocations to be chained.
