Added new flags to error checking of operands and function arguments. This is so that a context can be developed that is more forgiving about what can be put next to what. Such a context can NOT be used for evaluation or answer checking, but can be used to generate TeX output in more sophisticated situations.

Update to handle the fact that the Value package now includes the context with all MathObjects. (This may still need some work.)

Add a new operator // to be the same as / except its TeX form is a/b rather than \frac{a}{b}. This makes it possible get horizontal fractions in exponents, for example, where vertical fractions often don't look so good.

Eliminated unneeded parentheses in TeX output when unary minus and plus are used with fractions.

Added flags that control the reductions performed by Formula()->reduce. Each reduction operation can be individually enabled or disabled in the context, and in the reduce() call itself. More complex reductions need to be developed.

Improved TeX and string output in a number of situations. Improved use of parentheses to avoid things like x+-3. Fixed wrong parentheses in powers. Display (sin(x))^2 as sin^2(x) in TeX output.
