Adds Cylinder helper class for cylinder info access in grantlee templates to allow grantlee to access individual fields of the cylinder_t struct rather than a string representation of the whole cylinder info using a grantlee structure like this one: <table class="table_class"> <tr> <td>Cylinder</td> <td>Start press.</td> <td>End press.</td> <td>Gas mix</td> </tr> {% for cylinderObject in dive.cylinderObjects %} <tr> <td>{{ cylinderObject.description }}</td> <td>{{ cylinderObject.startPressure }}</td> <td>{{ cylinderObject.endPressure }}</td> <td>{{ cylinderObject.gasMix }}</td> </tr> {% endfor %} </table> Signed-off-by: Tim Wootton <tim@tee-jay.org.uk> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

#include "CylinderObjectHelper.h"
Cleanup: fold core/helpers.h into core/qthelper.h helpers.h included qthelper.h and all functions declared in helpers.h were defined in qthelper.h. Therefore fold the former into the latter, since the split seems completely arbitrary. While doing so, change the return-type of get_dc_nichname from "const QString" to "QString".

static QString EMPTY_CYLINDER_STRING = QStringLiteral("");
Cleanup: make cylinder_t argument to CylinderObjectHelper const CylinderObjectHelper copies state from the passed in cylinder_t but does not modify it. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

CylinderObjectHelper::CylinderObjectHelper(const cylinder_t *cylinder)
Cleanup: turn CylinderObjectHelper into value type CylinderObjectHelper is used for structured formatting of cylinder values in grantlee types. Instead of keeping a reference to a cylinder, turn it into a value type containing the formatted strings. This should be distinctly safer, as we don't risk having stale references flying around. Moreover, we don't have to use pointers but can use containers containing plain CylinderObjectHelper. Thus, no explicit memory management is needed, making the code distinctly easier to understand. Sadly, currently grantlee does not support Q_GADGET based Q_PROPERTY. Therefore a GRANTLEE_*_LOOKUP block has to be added. This can be removed in due course, as a patch to remedy this issue is in current grantlee master. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
