* Allocates memory and initializes the vertices.
|
* @param vertex is a structure holding information about

* vertices
|
* @param N is a number of vertices that are used in simulation
|
* @param zero_them is boolean value. 0 skip setting zeros to idx
|
* and (x,y,z) coordinates for each points, 1 means to zero all
|
* information on points > 1 requests zeroing of coordinates and
|
* indexing the vertices 0..N-1.
|
* @returns ts_bool value 1 on success, 0 otherwise
