/** @brief Creates initial vertex list
 *  
 *  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 vertexes 0..N-1.
 *	@returns ts_bool value 1 on success, 0 otherwise
