 +====== Print ======
  
 +###
 +For a wavefunction //psi//, //psi.Print()// prints the wavefunction //psi//. For small wavefunctions //print(psi)// is preferred over //psi.Print()//. //psi.Print()// is more memory efficient and therefore useful for large wavefunctions. //psi.Print()// returns //nill// and prints the wavefunction to standard output. Options can be specified if you want to print to file 
 +###
 +
 +===== Options =====
 +
 +###
 +//psi.Print()// accepts options. Several options are specified as a list //{}// of single options. A single option is given as a list of //name// and //value//, //{"name",value}//. 
 +###
 +
 +==== "File" ====
 +
 +###
 +"File" of type string: A string specifying the file name to which the wavefunction is printed (over writing the old file)
 +###
 +
 +==== "Full" ====
 +
 +###
 +"Full" of type boolean: A boolean character (standard false). If true additional information about Hash tables, fragmentation and collisions is printed. Only needed for debug or memory management optimization purposes.
 +###
 +
 +==== "Binary" ====
 +
 +###
 +"Binary" of type boolean: A boolean character (standard false). If true the wavefunctions are stored in binary format.
