Profiling in Instruments revealed a retain cycle problem. After dismissing FolioReaderContainer still keeps living along with several other objects (FolioReaderCenter, FolioReaderAudioPlayer and so on).
My commit only fixes a use case when FolioReaderContainer is modally presented and then immediately dismissed. No other interactions (e.g. chapter navigation, sharing etc.) were performed. So I suggest a better inspection.
I also noticed that in FolioReaderContainer.swift there are three static variables: readerConfig, epubPath and book. These variables also stay alive after dismissing VC. Maybe FolioReader is a better place for them?
