Improvement suggestions for d-decompose.js

[igavrysh]

• change introspect function so that it can handle objects included
• change introspect function so that it can handle recursive objects
• parseLines improvement so that it can process more than one space b/w parameter name and data type
• add support for curried functions multiline structure e.g.

'use strict';

const currdObj = { 
	common: {
			sum:  (
			// Partial sum apply, use first argument
			x // first argument which should support summation opertaion
			// Example: sum(1)
			// Returns: function(y) { return 1 + y }
		) => (
			// Apply curreied sum to second argument
			y // second argument which should support summation operation
			// Example: sum(1)(2)
			// Returns: 3
		) => (
			x + y
		) 
	}
};

introspect(currdObj)
