This snippet demonstrates how to get currently selected scene interface and
obtain number of mesh items in the scene from it.

Generally, selections are managed via selection service and are stored
as packets. So what we are doing is we are getting recent selection
of the cinema type from the selection service which comes as a pointer
to the selection packet. We then use scene packet translation object
to extract scene interface out of the packet we received pointer to from
selection service.

/* To read user value we spawn a new user value command.
 * Then, we are using the attributes interface set to the command
 * to set command's first argument to the name of the user value
 * that we want to read.
 * Next we obtain the index the of "value" argument so we can query
 * command for this argument and store user value's value in the value array.
 * The final step is to read the value from value array and put it
 * inside value int variable. In this case we know it's an int
 * so we go with GetInt() directly. If you do not know value's type
 * you can get it using .Type() method on the ValueArray interface.

/* This snippet demonstrates a function that will open a Yes/No dialog in MODO using dialog service.
 * 
 * To create a dialog we need dialog service. We use dialog service to allocate message object
 * that will determine the type of dialog that we will open and will contain the text of the message
 * that we want to display. The text needs to be set in the message table in a config file.
 * Next we set message object to our message passing message table name and message key
 * and we use SetCode() method to set the type of a dialog that we want to open.
 * Finally, we open such prepared message via dialog service
 * and translate the result into boolean value.
