binary operation output workspace problem

[Dickon Champion]

If i have two input workspace2D objects which contain data of dimension (X,Y)

the binary operation will create an output workspace2D of dimension (X-1,Y)

while the operation will fill data for the output workspace, the output is the wrong shape, and somewhere data will be lost

a unit test would have to be incorporated to test for the size of the output workspace to spot it

this is an error created by the blocksize function in the call on line 145 of BinaryOperation.cpp

there is an assumption being made that the x-array is the same length as the y-array data. this is not the case as it is a histogram and it is 1 value more, it is not a failure in the triple iterator. i think instead we just need a size_xarray function and maybe a size_xdata size_ydata function or something like that.....

[Dickon Champion]

ok as discussed, there is also a failure with the way the iterator works with respect to histogram/point data, needs a discussion within the team with options to continue forward with best solution
