//Use this function to turn a 1D sequence of elements that are logically grouped
|
|
//together by position into a 2D list. For example, if you have an input sequence
|
|
//like {A1, B1, C1, A2, B2, C2, A3, B3, C3} and you want to turn it into
|
|
//{ {A1, B1, C1}, {A2, B2, C2}, {A3, B3, C3} } you can use these functions to
|
|
//achieve that. You need to specify the size of the innermost groups, 3 in the
|
|
//example just given, and push_back() will automatically move to the next
|
|
//sublist every 3 items.
