Little bit of refactoring.  Added in lots more documentation.
large refactoring.  starting to think about tests.
First test down.  Lots of cleanup/refactoring already.  IMailInterceptor was the way to go.
Added IMailSender to allow customizing the mail sender and ease testing.  Also finished tests for now.
Silly me, named a test class improperly.  Fixed!
Bumping version number since the major overhaul/refactor.
Forgot some license headers.  Also cleaned up using statements.
Changing readme to refer to bitbucket wiki
EmailResult doesn't need to expose MailSender since MailerBase does already.  Also added another null check.
Attachments should work now.  All tests passing.  Woot!
Switched headers back to a dictionary.  Also bumped version number.
Adding support for inline attachments.
Added support for Reply-To header.  Added some documentation around Attachments.
UrlHelper extension methods for absolute urls are in, but still need testing.  More to come.
Bumped version to 0.3.1 and added NuGet support.  Still need to test helpers
Multi-part messaging support should be ready.  Need to test against Razor itself, but my own tests are passing.
Forgot license header
Fleshed out a few more tests around UrlHelperExtensions.
Adding some constructor tests for EmailResult.
Assigning content id based on the file name of the attachment.  This will make the html helpers much easier.
