Initial commit for starting adding 3D scans.  There are AM classes for the dacq scan controller as well as the scan and scan configuration that need to be built.  The others are the VESPERS specific subclasses that will inherit them.  VESPERSScanConfigurationView only needs to inherit the VESPERSScanConfigurationView that already exists.
Built the AM3DScan class.  Fixed the comment for the constructor in AM2DScan.  Fixes #424.
Fixed a bug in the copy constructor of AM2DScanConfiguration.  Got all the required information into AM3DScanConfiguration which is most of the work towards #423. Still needs testing and needs to be registered.
