WIP: Avoid going to QASM text unnecessarily (#273)
Remove intermediate QASM transforms: * New DagUnrolled created for dealing with unrolling from a DagCircuit instead of a QASM AST * JSON functionallity added to DagUnroller * expand_gates() method added to DagUnroller * Created a new static method for constructring a DagCircuit from a QuantumCircuit * default initializer name to init * updating initializer example to use default name * update qiskit_simulator extension. * Removed deepcopy() in two places to greatly improve performance. * Switched asserts to exceptions * Removed superfluous prints * Some minor refactoring to improve readability * Created tests for the DagUnroller * Removing some random behavior by switching normal dictionaries to OrderedDicts. * Fixing tests, linter and style. Some tests needed to be disabled for Python 3.5 due to inconsistencies with the use of dictionaries as ordered dictionaries.
