Add Score.UI Namespaces to web.config files for your Views

Every Views folder in your web project contains web.config file with some required information. 

One of the sections contains registered namespaces that allows committing them in Razor Views.

Find that sections and new Score.UI names:

          <add namespace="Score.UI.Data.DatasourceItems"/>
          <add namespace="Score.UI.Web"/>
          <add namespace="Score.UI.Web.Helpers"/>
          <add namespace="Score.UI.CCF" />
