 /**
 * This adapter provides an interface to use the SerializeIF functions
 * with arbitrary template objects to facilitate and simplify the serialization of classes
 * with different multiple different data types into buffers vice-versa.
 *
 * Examples:
 * A report class is converted into a TM buffer. The report class implements a serialize functions and calls
 * the AutoSerializeAdapter::serialize function repeatedly on all object data fields.
 * The getSerializedSize function is implemented by calling the
 * AutoSerializeAdapter::getSerializedSize function repeatedly on all data fields.
 *
 * The AutoSerializeAdapter functions can also be used as an alternative to memcpy
 * to retrieve data out of a buffer directly into a class variable with data type T while being able to specify endianness.
