TypeScript support

[xiaodeaux]

Just adding an issue to keep track of any progress towards supporting TypeScript. <3

Yeah, that would be great!

@Bogdan-Lyashenko maybe you can give a quick roadmap what has to be done to plugin the TS AST-Parser?

It might be quite some work to implement it, but if you can outline out the starting points, someone could begin to do it. Is there more to do to support TS than plugging in the Parser? Maybe you can comment if the rendering has to be modified as well.

TS mostly adds Type Parameters to functions, tokens, expressions, ...

@wtho I've updated babel to 7nth version recently to support TS. Now if you try something like const a: string = 'abc' it should work (parser will not fail). I think only 'converter' functions will be affected, meaning, what exactly should be displayed inside blocks in flowchart.
