LaTeX preview
Improved 'preview' function it self and its documentation.
Added also several wrappers (like pngview). This version
is integrated with new LaTeX printer ('inline' keyword).
I have rewriten LaTeX code generation almost from
scratch. Now it supports:
- almost all functions (zeta missing)
- multivariable derivatives
- proper fractions
- additional symbols
- proper brackets
- square roots
and so on.
I also added the 'inline' key word to both LatexPrinter
and latex(). If it is set to True, the printer will
generate inline code $ $. Otherwise enclose the
expression in 'equation*' environment.
Added support for typestting lists, tuples, dicts
and matrices (using math-mode for all).
Swiched from as_numer_denom() to fraction() to avoid
putting expressions like 1/(1+1/x) together.
