scope fixed, @ignore implemented

i have addressed these 3 points

1. @method is required, if I omit it (as you mentioned), no output is generated for that function
2. @ignore is ignored
3. Is it possible to hide the scope-line: 'Scope: inner function of MapView' ?

points 1 and 3 are caused by this jsdoc bug: https://github.com/jsdoc3/jsdoc/issues/685.. the work-around is to change `function MapModifier(options)` to `var MapModifier = function(options)`.. once you use this style, you no longer require @method.. 

I have implemented @ignore in the latest jsdoc2md.
