Java offers two kinds of multi line comments /** and /*.
The first is called Javadoc and ends up in generated API documentation
and is displayed by IDEs. The second is a multi line comment that does
not show up.

There are several places there /* instead of /** is used for API
documentation.

The optional ResultSet#getObject(int, Class) and
ResultSet#getObject(String, Class) methods are currently not
implemented.

Besides the conversions mentioned in appendix Appendix B, Table B-3 we
also support uniqueidentifier <-> UUID.

This commit does not include support for JSR-310 data types in order to
keep it smaller.

Fixes #6

UTC is an enum with one constant and a static variable. It has the
following comment

> The enum type delays initialization until first use.

This is demonstrably wrong.

The static variable is initialized when the class is initialized. If we
look at the decompiled static initializer of UTC we see that.

```
  // access flags 0x8
  static <clinit>()V
   L0
    LINENUMBER 522 L0
    NEW com/microsoft/sqlserver/jdbc/UTC
    DUP
    LDC "INSTANCE"
    ICONST_0
    INVOKESPECIAL com/microsoft/sqlserver/jdbc/UTC.<init> (Ljava/lang/String;I)V
    PUTSTATIC com/microsoft/sqlserver/jdbc/UTC.INSTANCE : Lcom/microsoft/sqlserver/jdbc/UTC;
    ICONST_1
    ANEWARRAY com/microsoft/sqlserver/jdbc/UTC
    DUP
    ICONST_0
    GETSTATIC com/microsoft/sqlserver/jdbc/UTC.INSTANCE : Lcom/microsoft/sqlserver/jdbc/UTC;

    MAXSTACK = 4
    MAXLOCALS = 0
