Create an algorithm to allow the definition of the sample shape

[Nick Draper]

REQUIRES #444

The underlying algoirthm is simple. An example of converting XML into an object is in FindDetectorsByShape.

The complex part is defining an easy to use GUI for this.

(In [2330]) Added start of the algorithm and GUI to create the sample shape. The algorithm doesn't do anything yet and isn't actually even registered with the factory. The GUI has most of the basic functionality needed but I still need to work out how to parse the binary tree properly to create the required XML string. Re #451

(In [2338]) Sample class now stores the sample geometry. Updated CreateSampleShape algorithm to use this and added accompanying test. Re #451

(In [2339]) As usual I forgot the DLLExport directive. Re #451

(In [2340]) Added CreateSampleShape class to Visual Studio solution. Re #451

(In [2341]) CreateSampleShapeDialog - Tidyed up code to create each shape details box and deletion is now recursive. Also removed 3D view until we are ready to implement it. It's usuable but confusing without the 3D view. Re #451

(In [2342]) Added the rest of the shapes defined in Mantid Geometry to shape dialog. Re #451

[Martyn Gigg]

The algorithm and a basic GUI now exist for this so I'm closing this but creating a new ticket, #535, to implement the 3D visualisation and better view of the binary tree .
