Issue on tracing anonymous functions

[gafreax]

I write some update that show the name of the anonymous function and also add the line number.

Also related to these issues:
issue 4
issue 5

The output now will be

./index.js: 59 (ERROR)
  [line: 76] anonymous: addToList: 24 (ERROR)
  [line: 58] anonymous: buildLevel: 6 (OK)
  [line: 44] anonymous: isAligned: 5 (OK)

The output with JSON format will be:

[
  {
    "file": "./index.js",
    "functionComplexities": [
      {
        "name": "anonymous: addToList",
        "complexity": 24,
        "line": 76
      },
      {
        "name": "anonymous: buildLevelsList",
        "complexity": 6,
        "line": 58
      },
      {
        "name": "anonymous: isAligned",
        "complexity": 5,
        "line": 44
      }
    ]
  }
]
