Add Summations: Logarithms #1

[RubyTheRoobster]

This issue, in accordance with the roadmap, aids with the implementation of logarithms by implementing special operators and summations.

The syntax for special operator calls:

\opName(arg1,arg2,arg3,...,argn)\ where arg1 .. argn is a list of functions and/or constants and parameters.

Edit: after a function is listed in arg1 .. argn, the types of the arguments must be listed after the arguments like this:

f(x1, x2, x3, .., xm)(type1, type2, ..., typen)(Return)

This is to make it possible for Operators to identify the types of constants.
