Add an example demonstrating isopycnal heaving and water mass transformation decomposition

[Oler2008]

Create a new documented example to decompose temperature (or other scalar) anomalies into isopycnal heaving (HVE) and changes along isopycnals (WMP)

[Oler2008]

Bins for potentital density 250: np.arange(1026.5,1029.1,.02)

Here is my code.

Hi both, could we update the issue title to be more descriptive? I personally don't know what these acronyms are... perhaps just spell them out?

[Hangyum]

Hi Navid, HVE means changes in temperature/salt/age by isopycnal heaving, and WMP means changes along the isopycnal. @Oler2008, could you spell out the WMP?

[navidcy]

Please edit the PR title and spell these things out -- thanks!

[navidcy]

@Hangyum or @Oler2008? Could you please update the issue title?

[Hangyum]

Yes Navid, I am changing this title now. I was waiting for Ole's response, but does the title look easier to read?

[navidcy]

It's words now that mean something! Thanks!!

Hi @Oler2008, could you send me your codes by using xhistogram to bin isopycnals? I can combine them.
