Added matrix_look_at. Added generators for matrices. Added project vector onto vector

[rgozim]

Added some functionality that was present in cml 1.0 and added a function for projecting a vector onto another vector. This could be helpful in implementing a new orthonormalise function.

Probably could do with some clean up on the comments.

Awesome, thanks! I'm still getting to know GitHub (and git), so it might take a day or two to get this merged. I also want to put in a couple of unit tests to cover your new code. If you have Boost.UnitTestFramework available, feel free to add whatever tests you'd like. Otherwise, I am happy to add them if you are okay with me doing so.

[rgozim]

No problem, there's still lots of things I'd like to try adding, just need to get more familiar with the library. I'll have a look over your test implementations and see if I can add some unit tests of my own.

[demianmnave]

Awesome, please get in touch if you have any questions.

Also, which compiler(s) are you currently using?

[demianmnave]

Hi Riad, sorry I haven't merged your changes yet. I noticed that you put the new code into matrix/projection.{h,tpp}, but it really belongs in transform.{h,tpp}, so I'm moving the code and adding a couple of tests to boot. You'll see what I've done when you grab the changes on your end.

No problem Demian. Thanks for implementing the tests. I've been mobbed with work for the past few weeks so I've not had a chance to create them.

Also, I'm using Visual Studio 2015.

[demianmnave]

No worries!  And 2015 is on my list to test, but let me know if
  you see anything
  funny happening if you get a chance to play around with my changes.

  Thanks, Demian
