# Description:

# Functions for generating CHCICommandBase derived classes.

# Attempts to fill in provided file templates with values deduced from the 

# command name and command parameters.

# Template substitutions are:

# $CLASSNAME: CNameOfCommand, where NameOfCommand is given as parameter.

# $FILENAME: namofcommand, lower case version of NameOfCommand. Used when substituting filename.

# $HEADERGUARD: NAMEOFCOMMAND, upper case version of NameOfCommand. Used as header guard define.

# $PARAMETERS: Type1 aParam1, Type2 aParam2, etc. List of parameters. Used in NewL and constructor definitions and implementations.

# $MEMBERS: Type1 iParam1; Type2 iParam2; etc. Class member declarations.

# $NEWL_DEFINITIONS: static $CLASSNAME NewL(); and if parameter count > 0, static $CLASSNAME NewL($PARAMETERS);. NewL definitions.

# $NEWL_IMPLEMENTATIONS: Implementations of the NewLs.

# $CONSTRUCTOR_DEFINITION: Constructor definition. A class always has a default constructor.

# $CONSTRUCTOR_IMPLEMENTATION: Constructor implementation.

# $DESTRUCTOR_IMPLEMENTATION: Destructor implementation.

# $WRITE_FRAME: Code to write command data to a CHctlCommandFrame.

# $COMMANDFRAME: Comments out CHctlCommandFrame parameter of the WriteFrame method of commands that have no data. This to avoid compiler warnings.

# $MEMBER_ASSIGNMENT: iParam1 = aParam1; For Reset implementation.

# $ACCESSOR_DEFINITIONS: Type1 Param1(); Parameter getter method definition.

# $ACCESSOR_IMPLEMENTATION: Type1 $CLASSNAME::Param1() { return iParam1; }. Parameter getter method implementation.

# $EVENT_MATCH_DEFINITIONS: Definition of the event matching methods

# $EVENT_MATCH_IMPLEMENTATIONS: Implementations of the event matching methods

# $EVENT_MATCH_INCLUDES: System includes required by event matching methods

# $GENERATE_TIME_STAMP: timestamp showing when the generator produced the file

# $PRAGMA_HW_VOICE_SETTING_ADVICE: Write pragma lines for commands setupsynchronousconnection and writevoicesetting
