Suggest you commit to sandbox

Looks plausible but I've not checked in detail.

You need a test suite - follow the examples for similar distributions?

Don't forget to say where you got the test values from (Wolfram, Matlab...)
in comments.
We've tried to use a variety of sources to reduce the risk of mistakes.
I have MathCAD but it doesn't calculate Laplace I think.

I find using MSVC IDE helpful for testing the test, but then you can add to
the test jamfile.v2

"Run test_laplace.cpp"

Good idea to cut your teeth on a simple distribution before trying to run
with a multivariate one ;-)
