/*! XByteArray represents the content of QHexEcit.
XByteArray comprehend the data itself and informations to store if it was
changed. The QHexEdit component uses these informations to perform nice
rendering of the data

XByteArray also provides some functionality to insert, replace and remove
single chars and QByteArras. Additionally some functions support rendering
and converting to readable strings.
