Implement a Rebin Algorithm

[Nick Draper]

Look to the implmentations within LibISIS and opengenie for inspiration

This is a simple routine to rebin a Workspace1D, it will be changed to rebin a workspace in general in due course. the inputs are simply xlo,delta,xhigh,distribution, which will be changed when the properties can be made to allow array Input

small change needed fabs() not abs() on a function

[Dickon Champion]

(In [759]) re #93

1) SimpleRebin generalised to be possible for Workspace1D or Workspace2D Input 2) required implementation of init() function which allocates memory and initializes all arrays to zero (X,Y,E,E2) 3) Workspace_sptr WorkspaceFactoryImpl::create(const std::string& className, const int& NVectors,

const int& XLength, const int& YLength) is now fully implemented and allocates memory for workspace1D, Workspace2D and

Managed Workspace2d, assumption is that Workspace1D will never be so long as to need a managed workspace, exception in place just in case

fixed slight error with distribution/non-distribution calculation of errors

[Dickon Champion]

(In [762]) re #93

implementing init() function in workspacefactory and property unit tests

[Dickon Champion]

(In [787]) re #93

errors are calculated according to OPENgenie formulism, array input of rebin parameters using ArrayProperty definition with string input

will now do some test functions....

[Dickon Champion]

(In [789]) re #93

errors other than gaussian cannot at the moment be calculated for rebin function, an appropriate error will be thrown a test function for the distribution/non-distribution workspaces1D/2D created for logarithmic and non-logarithmic binning combinations
