- Add brief style guide

STYLE

@@ -0,0 +1,42 @@
+Rather than write a style guide, please follow by examples you see in the code.
+If you send me a patch, I will not reject it for style reasons (but I will fix
+it before it gets committed) 
+
+* indentation: 2 spaces
+* between methods: 1 line
+* sort your requires
+* long lines should wrap at 80 characters. If you wrap at an operator (or, +,
+  etc) start the next line with that operator.
+* explicit is better than implicit
+
+The point is consistency and documentation. If you see inconsistencies, let me
+know, and I'll fix them :)
+
+Short example:
+
+require "something from a gem" # from gem 'thing'
+
+# some documentation about this class
+class Foo < Bar
+  # some documentation about this function
+  def somefunc(arg1, arg2, arg3)
+    # comment
+    puts "Hello"
+    if (some_long_condition \
+        or some_other_condition)
+      puts "World"
+    end # if <very short description>
+
+    # Long lines should wrap and start with an operator if possible.
+    foo = some + long + formula + thing \
+          + stuff + bar;
+
+    # Function calls, when wrapping, should align to the '(' where reasonable.
+    some_function_call(arg1, arg2, arg3, some_long_thing,
+                       alignment_here, arg6)
+    # If it seems unreasonable, wrap and indent 4 spaces.
+    some_really_long_function_call_blah_blah_blah(arg1,
+        arg2, arg3, arg4)
+      
+  end # def somefunc
+end # class Foo
