Jun.30.2018 -- CAlive to add sections and reset command

[Rick C. Hodgin]

CAlive will introduce section {{..}} blocks, and a new reset command to reset those memory blocks to 0 by default, with an optional parameter allowing it to be reset to that byte value.

    struct SExample

    {

        section linklist {{

            struct SLinkList ll1;

            struct SLinkList ll2;

        }}   // Since this one is not nested, doesn't need closing

             // "section linklist" text

        section data {{

        section integers {{

            int a;

            int b;

            int c;

            int d;

        section floats {{

            union {

                int ei;

                float ef;

            }

        section integers }}

            float f;

            float g;

            float h;

        section floats }}

        section data }}

    };

In this example, there are four sections defined:  linklist, data, integers, floats.  Some sections overlap, but each one is defined within its {{ and }} named range.

It would allow commands like this:

    struct SExample e;

    reset e;           // memset(&e, 0, sizeof(e));

    reset e.linklist;  // memset() only the linklist {{..}} members

    reset e.data;      // memset() only the data {{..}} members

    reset e.integers;  // memset() only the integers {{..}} members

    reset e.floats;    // memset() only the floats {{..}} members

In addition, it would allow member sections to be passed by address or reference, allowing for this:

    my_function(&e.data);

    void my_function(struct SExample.data* d)

    {

        // Reference only the SExample.data members here through d->

    }
