Version 3.0.0 (???)

• Fixed some issues with leading minus signs. (See #18 and #21)
• Changed the rounding behavior of round from MidpointRounding.ToEven to MidpointRounding.AwayFromZero. This means 0.5 goes to 1 instead of 0.
• Added the boolean operators ">=", "<=", "!=", and "==". (See #20)
• Fixed a divide-by-zero error with the "/" and ":" operators. They now return zero in such case.
• Only target the .NET Standard (1.0 - 2.0).
• Added MathParserException for parser-related exceptions.
• Added random to the list of predefined functions for getting random numbers within a range:

- 0 arguments: 0 inclusive - 1 exclusive
- 1 argument : 0 inclusive - arg1 exclusive
- 2 arguments: arg1 inclusive - arg2 exclusive

• The variable declarator ("let") may now be changed.
• Fixed an issue where numbers would lose their sign.
• Added BooleanParser for parsing and evaluating boolean expressions.
• Added ScriptParser and other related items for parsing and evaluating "script"-like expressions.

ScriptParser can handle things like if statements:

let x = 5

0
if (x >= 4)
    1

end if

• Added more unit tests.
• Documentation improvements.
• Simplified some internal logic.
• Other small changes and improvements.
