| make_lp
						Create and initialise a new lprec structure. 
						lprec *make_lp(int rows, int columns); 
						Return Value 
						Returns a pointer to a new lprec structure. This must be provided to almost all
						lp_solve functions.A NULL return value indicates an error. Specifically not enough memory
						available to setup an lprec structure.
 
						Parameters 
						rows 
						Initial number of rows. Can be 0 as new rows can be added via 
							add_constraint, add_constraintex, str_add_constraint 
						columns 
						Initial number of columns. Can be 0 as new columns can be added via 
							add_column, add_columnex, str_add_column 
						Remarks 
						The make_lp function constructs a new LP. Sets all variables to initial
						values.The LP has rows rows and columns columns. The matrix contains no
						values, but space for one value. All arrays that depend on rows and columns
						are allocated.
 
 It is advised not to read/write the lprec structure. Instead, use the function
						interface to communicate with the lp_solve library. This because the structure
						can change over time. The function interface will be more stable.
 
						Example #include <stdio.h>
#include <stdlib.h>
#include "lp_lib.h"
int main(void)
{
  lprec *lp;
  /* Create a new LP model */
  lp = make_lp(0, 0);
  if(lp == NULL) {
    fprintf(stderr, "Unable to create new LP model\n");
    return(1);
  }
  /* Model created */
  /*

  delete_lp(lp);
