[#24] Example App has essential buttons hidden under nav bar.

Set frames: a bit verbose but gets the idea across.
Now the buttons are visible on the bottom of view.
Mainly an accent change to use Objective-C style.
fixes #26
Objective-C specific syntax fixes:
  Verbose naming of methods, adhering to naming conventions
  Passive return for nil values
  No need to synthesize
  Eliminate nil checks through ‘==‘
  Eliminate more ‘new’ as allocation and initialization should be separated.
  Use custom initialization for dictionaries and arrays for safer type
  Separation of allocation and initialization: no more allocating memory when we don’t have to.
Completely backward compatible
Other caveats that came with idiomatic Objective-C
  Safer setObject:forKey: by having early returns if there is no explicit format (to prevent crash)
  Simplified logic in conditions
  Simplified(?) loops through routes using faster enumeration with blocks
  Add explicit factory class methods for constructions
  Add default routerOptions
Want to do (but didn't/haven't) to adhere to usual Objective-C style
  Want to get rid of custom new (newRouter)
  Want to have better error handling; no more exception throwing so we get verbose debugging info
  Want to simplify controllerForRouterParams and routerParamsForUrl more
  Want to get rid of register_name by defining selector macros
  Want to replace property shouldOpenAsRootViewController in routerOptions into root’ with getter ‘isRoot’ to parallel modal
  Not sure: routerOptions: want to not have wrappers around setters but users might want to keep DSL-style chaining.
  Not sure: should I fix spacing more?
  Not sure: should callback in options be overridden, ever?
Functionality \todo: have both call back and ‘open’ in options.

Minor fixes on documentation and slight logic unrolling

Changed spacing back.

Minor change; separated two issues.

reverted example app to Aug 5.

more sample app struggle.
