Merge pull request #2 from pwcazenave/karen

Merge in your new functionality with my dev version. This also makes the new functions optional whilst still maintaining the ability to use the new functions.
Update interp1 function to use pchip instead of csap as the latter will be removed in a future version of MATLAB and the innumerable warnings were doing my nut in. I checked the output using the new interp1 call and it's identical to the old version. Also update the parallel toolbox stuff for the same reason (future removal).
Fix the check for whether the parallel pool is open when using the new tools.
Fix indent.
Merge branch 'dev' of github.com:kjamoudry/fvcom-toolbox into dev
Add new functionality to exclude specific rivers from the model input. This is useful if you know that some of your river data is a load of rubbish and you want to exclude that specific one, or if you want to look at the impact of a given river on the system you are modelling.
Fix typo in Karen's name.
Move to the new version of the parallel tools for MATLAB and remove the old code.
Add a HORRIBLE HACK to fix the time problems I have with this.
Add new option to use an alternatively formatted input climatology (two columns instead of the number in the EHYPE data). This meant I had to be a bit more sensible with handling unexpected formats and differently sized arrays, hence the rather large changeset.
Add new field to the mesh object to indicate whether the model has rivers. Also update the river functions to use that field and also populate the existing field with the number of rivrs in it.
Fix issues with the climatology vs. timeseries allocation of the output arrays.
Add the calculation of the end day for the multiyear climatology to be within the loop through all the years so that leap years are accounted for properly. Also correct the number of days by which to pad the leap year data.
Fix the creation of the Itime2 variable (milliseconds since midnight) which was previously omitted from the new restart file. Also update the help to better describe how the optional out_date argument works.
Fix bug in interpolating in the vertical when HYCOM data has only a single depth bin. The fix repeats the existing value down the entire FVCOM water column.
Update the ChangeLog with the latest changes from the dev branch.
