Command: repeat
 
Syntax: 
  s = repeat(x, a)
  
Description: 
  Create a sequence of length a where each element is x.
  
Comments: 
  When you repeat a sequence or a floating-point number the
  interpreter does not actually make multiple copies in memory.
  Rather, a single copy is "pointed to" a number of times. 
  
Example 1: 
   repeat(0, 10)      -- {0,0,0,0,0,0,0,0,0,0}
    
Example 2: 
   repeat("JOHN", 4)  -- {"JOHN", "JOHN", "JOHN", "JOHN"}
