* added an informative error message when dat.paths is not present

* added an identifier to the error message

* Added warnings and errors to deal with the case that hardware.mat is not found

* Changed error identifiers following Miles' suggestion of module:package:function:error

* added more info to error for empty rig

* added more info to no dat.paths error
