// MOCA_ENTRY_POINT( <main object class> )

// The MOCA_ENTRY_POINT macro is used to define the exported function that
// Origin will use to communicate with your DLL.  The macro takes a single
// argument, the class name of your main object.

// Property Map:
//
// The Property Map is for declaring the properties of your LabTalk object.
//
// A property is mapped to Get and Set function.  These functions allow
// you to do error checking or any necessary conversions.  A read-only
// property can be declared by using the _GET macro.
//
// MOCA_PROP_INT( <GetFunction>,<SetFunction>,<PropertyNameStr> )
// MOCA_PROP_REAL( <GetFunction>,<SetFunction>,<PropertyNameStr> )

// MOCA_PROP_INT_GET( <GetFunction>,<PropertyNameStr> )
// MOCA_PROP_REAL_GET( <GetFunction>,<PropertyNameStr> )
// MOCA_PROP_STR_GET( <GetFunction>,<PropertyNameStr> )
//
// A Simple Property is mapped to a data member.  There are no Get/Set
// functions for a Simple Property.  MOCA will take care of the assignment.
// A simple read-only property can be declared by using the _GET macro.

//
// <MemberFunction> must be declared as "BOOL foo(double &, CStringArray &);"
// The double is used for storing LabTalk's return value.
// The CStringArray contains the arguments passed from LabTalk.
