Vector and Matrix support

[Former user]

Originally reported on Google Code with ID 220

OOOOPS,

Not a bug report really.  Wrong place..  but 2 good suggestions.

1)  Matrix capability.   X=(5;4;2|4;3;2|2;2;3)  plus functions for them, 
dot products, etc...   and being able to do sin(x) and have it return an 
array of sines or something.

2)  Custom functions.  If say you enter Y(X;Z)= 14*x/((x*z)^2).  This 
would store as a custom function and one could enter y(4;5) and get the 
result or use their own current variables.

``` Hi, thanks for the suggestions. Regarding 2), it's a duplicate of issue 38. Regarding

1), it's something planned for a long time and is dependent on the new parser, but

now we have a task created here to remind about it :) ```

Any way I could help with the matrix support?

@frodobagginsfll Nothing has ever been done in that matter al this time. Please feel
free to come up with something. This has to be done at the parser level, making it
able to recognize at least one of:
    foo=[1;2|3;4]
    foo=[1;2][3;4]
    foo=[[1;2][3;4]]
and add built-in support for a matrix value type in the higher-level math engine side
(hmath).

@heldercorreia Could you give me an overview of how the parser is structured?
