Determine READS groups/variables more accurately

If a local variable is read from a grid function, but later overwritten before its value is used, don't count them as READS groups.
Expand dummy indices in a particular order to reduce code size

Expand less-often occurring dummy indices first to reduce the size of the generated code.
Correct name of paramcheck routine
Correct error in parenthesis handling

Don't use string patterns to remove parentheses. (This removes the outermost parentheses e.g. from (a || b) && (c || d), leading to syntax errors.)

Match And and Or expressions with multiple arguments to reduce number of parentheses.
