DocumentUltimate 2.1.4

## Version 2.1.4 - December 5, 2016

- **Added:** Static Convert methods to DocumentConverter class for convenience. For a quick conversion
 especially when the input file will be converted once, static Convert6 method overloads can preferred
 instead of creating a DocumentConverter instance and calling instance ConvertTo method.

- **Added:** Static EnumeratePossibleOutputFormats and EnumeratePossibleInputFormats methods to DocumentConverter
 class. EnumeratePossibleOutputFormats enumerates possible output document formats for a given input document
 file/format. EnumeratePossibleInputFormats enumerates possible input document formats for a given output document
 file/format.

- **Fixed:** DocumentConverter.CanConvert method was broken.

- **Fixed:** In some cases you would still receive this dreaded error when opening a document in DocumentViewer:
 The type initializer for 'GleamTech.DocumentUltimate.DocumentConverter' threw an exception.
 This happened when the web application used a custom object derived from IPrinciple (custom authentication module).
 Loading mixed-mode DLLs causes cross AppDomain call and serialization occurs. Thread attached objects like
 custom principal (i.e. set via Thread.CurrentPrincipal) could not be serialized because it's DLL was not found
 so this in effect prevented loading of the mixed-mode DLL

- **Improved:** Updated example projects Mvc.CS and Mvc.VB from ASP.NET MVC 3 to ASP.NET MVC 4 so that they can
 be properly edited (no Razor warnings) in Visual Studio 2015 while keeping compatibility back to Visual Studio 2010.
 Also added ASP.NET MVC 4 as Nuget references so that it can be restored automatically when project is ran in
 Visual Studio.
