 +====== Name ======
  
 +###
 +string, read and write.
 +###
 +
 +###
 +A string representing the name of the operator. The name of the operator is printed during print statements and error messages. Note that the name of the operator is not the same as the variable name that stores the operator.
 +###
 +
 +===== Example =====
 +
 +###
 +We define:
 +$$O=3.4+1.2a^{\dagger}_{0}\,a^{\phantom{\dagger}}_{0}+(2.5+I)a^{\dagger}_{1}\,a^{\phantom{\dagger}}_{2},$$
 +and print the name of the operator (standard name of operators is "Operator"). Next we change the name and print the full operator.
 +###
 +
 +==== Input ====
 +<code Quanty Example.Quanty>
 +NF=3
 +NB=0
 +O = NewOperator(NF,NB,{{3.4},{0,-0,1.2},{1,-2,2.5+I}})
 +print(O.Name)
 +O.Name = "My test operator"
 +print(O)
 +</code>
