// Description: The Tube class simply determines the attributes of a tube
// object and what methods act on a single tube. 
//-----------------------------------------------------------------------
// NOTE: The information in tubetest.json is still in the file, so when 
// the program is run, a print statement appears saying "You've loaded
// a tube at (300, 306)".
