/**
* The PofWriter interface provides the capability of writing a set of
* non-primitive types ("user types") to a POF stream as an ordered sequence
* of indexed properties.
*
* The serialized format of a POF user type is as follows:
* <ul>
*   <li>Type Identifier</li>
*   <li>Version Identifier</li>
*   <li>[Property Index, Property Value]*</li>
*   <li>-1</li>
* </ul>
* The type identifier is an integer value greater than or equal to zero that
* identifies the non-primitive type. The type identifier has no explicit
* or self-describing meaning within the POF stream itself; in other words,
* the type identifier does not contain the actual class definition. Instead,
* the PofWriter and corresponding {@link PofReader} share a
* {@link PofContext} which contains the necessary meta-data, including type
* identifier to type mappings.
*
* The version identifier is used to support both backwards and forwards
* compatibility of serialized POF user types. Versioning of user types allows
* the addition of new properties to a user type, but not the replacement or
* removal of properties that existed in a previous version of the user type.
*
* When a version <i>v1</i> of a user type written by a PofWriter is read by
* a PofReader that supports version <i>v2</i> of the same user type, the
* PofReader returns default values for the additional properties of the User
* Type that exist in <i>v2</i> but do not exist in <i>v1</i>. Conversely,
* when a version <i>v2</i> of a user type written by a PofWriter is read by
* a PofReader that supports version <i>v1</i> of the same user type, the
* instance of user type <i>v1</i> must store those additional opaque
* properties for later encoding. The PofReader enables the user type to
* store off the opaque properties in binary form (see {@link
* PofReader#readRemainder PofReader::readRemainder}). When the user type
* is re-encoded, it must be done so using the version identifier
* <i>v2</i>, since it is including the unaltered <i>v2</i> properties. The
* opaque properties are subsequently included in the POF stream using the
* {@link #writeRemainder} method.
*
* Following the version identifier is an ordered sequence of index/value
* pairs, each of which is composed of a property index encoded as
* non-negative integer value whose value is greater than the previous
* property index, and a property value encoded as a POF value. The user type
* is finally terminated with an illegal property index of -1.
*
* Note: To read a property that was written using a PofWrite method, the
* corresponding read method on {@link PofReader} must be used. For example,
* if a property was written using {@link #writeByteArray},
* {@link PofReader#readByteArray PofReader::readByteArray} must be used to
* read the property.
