Ability to use asciidoc for package documentation

Now it searches for overview.adoc and _design/overview.adoc by default and use those as package documentation instead of go package documentation. Those are included in the document as reference and hence the absolute path must be preserved.

It is possible to override using -d relative-file-path (support multiple -d).

Fixed bug in main

Emitted debug log to stdout

Bugfixes and template support

v0.0.8

fixed typo in readme

Better handling of newline when rendering

v0.0.7

render proper newlines

Nested Structs and non primitive type support

Now it supports both nested structs and typedefs where the type is of struct kind like time.Time.

// MyStruct is a structure of nonsense
type MyStruct struct {
	// Inline the struct
	Inline struct {
		// FooBar is a even more nonsense variable
		FooBar int
	}
	// MyInt is happy to be after Inline
	MyInt int
}

This generates the following ASCIIDOC

=== MyStruct
[source, go]
----
type MyStruct struct {
	Inline	struct
	MyInt	int
}
----

MyStruct is a structure of nonsense

==== MyInt int
MyInt is happy to be after Inline

=== Inline
[source, go]
----
struct {
	FooBar	int
}
----

Inline the struct
==== FooBar int
FooBar is a even more nonsense variable

toc is default enabled and sorting of imports

v0.0.5

added sample godoc in readme

Tabify struct & interfaces

Use the tabwriter to align methods and fields to more mimic the golang code autoformatter.

Finalize and made it easy to install goasciidoc

Refactor and instructions to install goasciidoc is now done.

First release

This is the first release of goasciidoc command.
