// TODO Class to implement printing
// Since DICOM does printing ?
// Also I would like to encapsulate the IsCharacterPrintable thing
// (to avoid printing \0 and other weird characters)
// \todo I still need to implement skiping of group (shadow)
// need to implement longer field to read

/*
 * Output:
 * For ASCII:
 * Typically will look like:
 * [ORIGINAL\PRIMARY\OTHER]
 * If a non printable character is found: RED and INVERSE is used:
 * [                .]
 *
 * when the VR is not found (file or dict), we check if we can print the output:
 * on success ASCII mode is used, on failure the output is printed a series of bytes
 *
 * Special case when the data element is empty:
 * INVERSE << (no value)
 *
 * retired public element are printed in red and underline
 * unknown private element are printed in RED followed by 'UNKNOWN'
 *
 * Correct VR is printed in green just after the found VR
 *
 * length of data element is printed in bytes, followed by the VM, a green VM is appended
 * if this is not compatible
