Check that comments are handled correctly.

     3	* Verify initial status of vectors

Verify that the vectors are initialized correctly, and that the status command returns the correct set of
information for a vector that only contains zeroes.

     4	s 0
     5	s 1
     6	s 2

Fetching an element from a vector that only contains zeroes should returns a 0.

     7	? 0 5

Verify that all other vectors were left untouched by the previous command.

     8	s 0
     9	s 1
    10	s 2

Assigning a 0 to an index of the vector should not cause its status information to change.

    11	= 0 0 0

Verify that all other vectors were left untouched by the previous command.

    12	s 0
    13	s 1
    14	s 2

Verify that adding elements to a vector only containing zeroes is handled correctly as are all subsequent
additions.

    15	= 1 9 10
    16	= 1 2 -1
    17	= 1 100 101

Use the status to check the number of non-zero elements and range of indices for the non-zero elements to
ensure that elements were correctly added. Also serves to double-check the status command.

    18	s 1

Extend the index range in one direction, and fetch several elements (the first should be non-zero, the second
should be 0). Use the status command to verify that everything was done properly.

    19	= 1 -10 -9
    20	? 1 100
    21	? 1 99
    22	s 1
    23	ctkierst@fitch.math[34]% cat invalid

Test too few parameters.

    24	=
    25	= 0
    26	= x

Test an invalid vector specification.

    27	= 0 1
    28	= 9 1

Test invalid integer specifications.

    29	= 0 x
    30	= 0 1 x
    31	= 9 1 1 1
    32	= 0 1 1 x
    33	= 9 1 1

Repeat above tests on '?' and 's' commands.

    34	?
    35	? 9
    36	? x
    37	? 0 x
    38	= 9
