};Description
DVcomb_comp combines any combination of components of two Node_Data objects into one new Node_Data object with n components. The user should ensure that the nnodes of the two input Node_Datas are equal.
Input
An integer array of variable length. Sets which components to take from &nd1. For example, if comp1 = {0, 3}, then the first and fourth components will be extracted.
An integer array of variable length. Sets which components to take from &nd2. For example, if comp2 = {1}, then the second component will be extracted.
Output
This is a new Node_Data with the same number of nodes as the first input field, and n components (nnode_data), where n is the sum of the dimensions of comp1 and comp2. Its own Node_Data is a reference (*node_data) to an n object array, where the array values are references to the components in nd1 and nd2.
