 OptionDefinition class represents the option definition for single option
 instance. In particular, it holds data type (or data types) conveyed by
 the particular option. The data type may be any of predefined option
 types, e.g. uint8, uint16 etc, or it can be record of multiple different
 data types. Setting option type to 'record' allows to specify data types
 carried by the record. It is also possible to provide array indicator
 which specifies that there are multiple 'single values' or multiple
 'records' within the option. When OptionDefinition instance is created it
 returns the most appropriate 'factory' function to create the option for
 the specified definition. The 'factory' function uses raw buffer as an
 input to create the instance ot the option.
 The 'basic' implementation does not provide 'encapsulation' capabilities.
