`initWithCoder` not handled

[sroze]

Hi, and thanks for that component !

Btw, the initWithCoder method of BZGFormViewController isn't implemented.
That creates an infinite loop when its initializer is called.

As you can implement it or simply move style and formCellsBySection properties in the header file (and let developer initialize these values), I let you do the change :)
