Examples:
    Decompile assembly to console out.
        ilspycmd sample.dll

    Decompile assembly to destination directory (single C# file).
        ilspycmd -o c:\decompiled sample.dll

    Decompile assembly to destination directory, create a project file, one source file per type.
        ilspycmd -p -o c:\decompiled sample.dll

    Decompile assembly to destination directory, create a project file, one source file per type, 
    into nicely nested directories.
        ilspycmd --nested-directories -p -o c:\decompiled sample.dll
