2.0.0

Added support for compiling mathematical expression strings into executable code, producing a delegate that represents the expression.

Example:

var fn = "ln(1/x1 + √(1/(x2*x2) + 1))"
    .Compile(new { x1 = 0.0, x2 = 0.0 }, new ScientificMathContext());

var value = fn(new { x1 = -0.5, x2 = 0.5 });

This enhancement allows for efficient evaluation of complex mathematical expressions by converting them into callable delegates.

Added MathExpression class instead of the MathEvaluator class that combines evaluation and compilation. Static methods are removed.
