 For node and bond fields (constant and non-constant) the following options are possible.
 
 **Matrix style**
+
 You can switch between vector and matrix. If you give the keyword Matrix_or_Vector = "Vector" you get vector of length degree of freedom for each node or bond. If Matrix_or_Vector = "Matrix" each node or bond gets matrix dof $\times$ dof
 ```julia
 datamanager.create_node_field(Fieldname::String, Type_of_variable::Type, Matrix_or_Vector::String, Degree_of_freedom::Int64)
 ```
 **Pre-defined Values**
+
 You can add an optional value at the end. The default is zero.
