Multiple additions to front end

[Stephen Siegel]

Need to add:

pointer types, as in

int* p; /* pointer to int */
real*** q; /* pointer to pointer to pointer to real */
int[]* r; /* pointer to array of int */

user-defined record types, something like

typedef struct {
  int x;
  real[N] y;
} foo;

record navigation expression (f.x)

pointer dereference expression (*) and address-of operator (&)

allocate statements, for example

int* p;
p = allocate(int, 10);

deallocate statements, for example

deallocate(p);

Pointer types added to the front-end. Need more test examples.

[Stephen Siegel]

Added first simple pointer test. Looks good.
