Interface Updates
- Edit Titles in Pyramids and remove empty space in top categories with no values.
- Added combo box for years in Forecast Map and made base year default instead of First Year.
Model Updates
- Avoid start using convergence with year 2 which caused transients in PPP, like the case of Singapore and Sahrawi.


- Small transient in 2nd year for Land Forest:

- Initialization of GDP had a problem for the US, because Consumption for Services was reaching a limit, we have now relaxed the limit so that GDP is now back to initializing to the data value:

- Initialization of Governament Consumption for Singapore had a problem because Imports are relatively big for Manufactures, and were producing negative values in the shares used to compute Government Consumption by Economic Sector.
- Removed limit in PFD initialization that didn't allow negatives, this was altering PFD values values for Singapore, because again Imports are big in Energy, and produce a negative PFD value, which is now allowed but keeps everything in synch and fixes the drop we were seeing in the 2nd year due to GDPPOT.
