- use math.Sqrt instead of Math.sqrt
- use float64 for Point fields to match math.Sqrt
- distinguish between Point and Point3D for clarity
- add alignment sizes for complex types

Doing the tail recursion elimination explicitly
seems safer than leaving it to the compiler;
the code is still clean and easy to understand.

Before one could say
	{field}
or
	{field|formatter}
Now one can also say
	{field1 field2 field3}
or
	{field1 field2 field3|formatter}
and the fields are passed as successive arguments to the formatter,
analogous to fmt.Print.

Make them more like Printf, with a ... final argument.  This breaks
code with existing formatters but not the templates that use them.

Changed all uses of bytes.Add (aside from those testing bytes.Add) to append(a, b...).
Also ran "gofmt -s" and made use of copy([]byte, string) in the fasta benchmark.

This means that any Writer can be used safely
even when Output is called concurrently.

Make Split work on backslashes as well as on slashes under Windows
and support the "C:filename" special case. Also add corresponding
tests.
