/// @brief Subclass of <a href="http://qt-project.org/doc/qt-5/qfiledialog.html">QFileDialog</a>
/// @author Don Gagne <don@thegagnes.com>
/*!
Subclass of <a href="http://qt-project.org/doc/qt-5/qfiledialog.html">QFileDialog</a> which re-implements the static public functions. The reason for this
is that the <a href="http://qt-project.org/doc/qt-5/qfiledialog.html">QFileDialog</a> implementations of these use the native os dialogs. On OSX these
these can intermittently hang. So instead here we use the native dialogs. It also allows
use to catch these dialogs for unit testing.
@remark If you need to know what type of file was returned by these functions, you can use something like:
//! Static helper that invokes a File Save dialog where the user can select a directory and enter a filename to be saved.
/*!
@param[in] parent The parent QWidget.
@param[in] caption The caption displayed at the top of the dialog.
@param[in] dir The initial directory shown to the user.
@param[in] filter The filter used for selecting the file type.
@param[in] defaultSuffix Specifies a string that will be added to the filename if it has no suffix already. The suffix is typically used to indicate the file type (e.g. "txt" indicates a text file).
@param[in] strict Makes the default suffix mandatory. Only files with those extensions will be allowed.
@param[in] options Set the various options that affect the look and feel of the dialog.
@return The full path and filename to be used to save the file or \c QString("") if none.
@remark If a default suffix is given, it will be appended to the filename if the user does not enter one themselves. That is, if the user simply enters \e foo and the default suffix is set to \e bar,
the returned filename will be \e foo.bar. However, if the user specifies a suffix, the \e strict flag will determine what is done. If the user enters \e foo.txt and \e strict is false, the function
returns \e foo.txt (no suffix enforced). If \e strict is true however, the default suffix is appended no matter what. In the case above, the function will return \e foo.txt.bar (suffix enforced).
@remark If \e strict is set and the file name given by the user is renamed (the \e foo.txt.bar example above), the function will check and see if the file already exists. If that's the case, it will
ask the user if they want to overwrite it.
