ENH: added tic, tac, toc functions

[albop]

I always lack the tic, toc functions from matlab. Here is a trivial implementation. It works exactly like Matlab's version, has an additional tac() function.
Here is an example:

from quantecon.timing import tic,tac,toc

tic()  # initializes timer
for i in range(10):
    sleep(1)
    tac()   # prints: "Elapsed: 1 seconds."
toc() # prints: "Elapsed: 10 seconds."

This is cool, thanks for sharing.

One comment about the code is that we are really pushing numpydoc style docstrings. The only place I see in your code that could be changed to conform to that is in the main doctoring for the Timer class.

I fixed the docstring. Note that the object is not supposed to be used by
end users though. It should not be seen in generated documentation.

Thanks, this is neat. It might be appreciated by MATLAB refugees.
