Checker for variables use

Description

Check if a declared or uninitialized variable is used.

Initialized and unused variables are useless and can decrease the readability.

When an uninitialized variable is used its value is taken in the previous scope if defined so it could have side-effects.

Examples

function y=foo(x)
    scilab = 123;
    y = bar(x);
endfunction

function y=bar(x)
    Scilab = 456;
    y = scilab + 1; // typo error
endfunction
