Implement algorithm to apply angle-dependent transmission correction

[Mathieu Doucet]

The transmission correction algorithms currently implemented compute the transmission at theta=0. For shorter sample-detector distances, the transmission correction is a function of the transmission at theta=0 and the scattering angle.

Implement an algo that applies the angle-corrected transmission from the output of CalculateTransmission.

(In [5284]) Added ApplyTransmissionCorrection + tests. Re #1408

[Mathieu Doucet]

(In [5291]) Added test to check that we get the correct result even when the order of the monitors is not the spectrum/index order. Re #1408

[Mathieu Doucet]

(In [5336]) Modified ApplyTransmissionCorrection to accept transmission value entered by hand. Re #1408

[Mathieu Doucet]

(In [5337]) Fixed problem with ApplyTransmissionCorrection for when the output workspace is the input workspace. Re #1408

(In [5338]) Updated documentation in header file. Re #1408

Moved to verify state

There is a strange problem with TransmissionValue is exactly 1 e.g. the following gives all 1s on my computer

Load(Filename="C:/mantid/Test/Data/SANS2D/BioSANS_test_data.xml",OutputWorkspace="bioSANS")
ApplyTransmissionCorrection(InputWorkspace="bioSANS",OutputWorkspace="bioTRANS",TransmissionValue="1")
Divide(LHSWorkspace="bioSANS",RHSWorkspace="bioTRANS",OutputWorkspace="test")

Might not be a problem because other values work OK. There is not wikipage yet at http://www.mantidproject.org/ApplyTransmissionCorrection The algorithm leaves all the x values at 0

[Mathieu Doucet]

The correction goes like T^{(some factor). When T=1 there should be no correction.}

The wiki page will be taken care of in Iteration 25 (see #1557)
