Implement simple workspace operations (+,-,*,/, maybe ^)

[Nick Draper]

These should be implmented as operator overloads that simply call algorithms to do the job.

We need to define a chart of what operations between which workspaces are actually valid and enforce this.

Then it is possible that the use of STL iterators and function pointers may allow this to be done in a generic manner.

[Nick Draper]

Workspace Type	1D	2D	SingleValue	n-tuple	Abstract
1D	+,-,/,*	+,-,/,*	+,-,/,*
2D	+,-,/,*		+,-,/,*
SingleValue
n-tuple
Abstract

With similar workspaces the array bounds must match, and for 2D the Y axes values must match.

With 1D and 2D workspaces it should be assumed that this applies the same value across the Y axis, and therefor only the X axis must match.

Single values will apply to every cell.

[Dickon Champion]

(In [584]) add in extra x array checking for binary operations, in doing so removed workspace.getX/Y/E function to leave workspace.dataX/Y/E which either returns a const or non-const std::vector<double&>

changed getY/Y/E functions to call new function

re #59

[Dickon Champion]

(In [585]) changed getY/Y/E functions in test to call new function

re #59

[Dickon Champion]

(In [586]) changed getY/Y/E functions in test to call new function missed one...

re #59

[Dickon Champion]

(In [587]) and try again this time extra virtual functions in test/WorkspaceFactoryTest.h
