Add wiki page. To start with copy http://www.mantidproject.org/ExpDecay

In addition change the parameter names as follows:

A -> Height lambda -> Lambda frequency -> Frequency phi -> Phi

Note the fit function equation is then

Height * exp(-Lambda*x) * cos(2*Pi*Frequency*x+Phi)

Minor adjustment after speaking to Steve. He wants parameter 'A' to keep this name. So this means change of parameter names are:

A -> A

lambda -> Lambda

frequency -> Frequency

phi -> Phi
