MathML printing and parsing

@nishnik has been porting some of the relationals code into SymEngine. It's just a matter of porting this over. It should be easy to implement this although for the functionality...

MathML printing and parsing

@dladd, are you still interested in this?

MathML printing and parsing

MathML printing (not parsing) is available in master now

Should symengine throw a DomainError or NaN for sqrt(-1)

Neither IMO. Currently sympy and symengine returns `I`

WIP: BipartiteGraph and Hopcroft-Karp algorithm in C++

@Upabjojr, thanks for your work on this. I have two questions on the design decisions. 1. Do we need a `TEdgeValue value`? It seems unneeded. 2. The graph keeps left...

Add support for unknown functions

>Do you have a rough estimate of when this feature will be ready? Not at the moment.

LLVMDoubleVisitor init is slow, added example as benchmark

@certik, the first 2 timings are for 1 expression and the last 2 are a different expression. llvm timing shouldn't have had `with cache` or `without cache` in the description

@ichumuh, can you run callgrind on just the llvmvisitor call and post the the functions that take the most time?

I usually use `kcachegrind` to interpret the results.

Looking at the png, I don't think there's much we can do. You can try reducing the optimization level, but that would affect the runtime.
