Initial commit for MongoDB foreign data wrapper
Fixed the link to blog entry in README file
Removed .gitignore file
Add support for translating the BSON Object Identifier (_id)
Add nested field support.
Merge pull request #3 from davidcrawford/pull-nested

Add nested field support. The user can now declare a quoted column name separated by dots to access a nested field in a MongoDB collection. For example, a nested field "user" : { "first_name" : "David" } is declared with the quoted column name "user.first_name" in the PostgreSQL table.
Updated README to describe nested document field changes.
mongo_fdw is upgraded to postgresql-9.2 including analyze feauture.
Add .gitignore file

Used the C template from https://github.com/github/gitignore
Remove existing mongo-c-driver directory

It'd have conflicted with the submodule.
Add back mongo-c-driver as submodule, lock to v0.6

Slightly better dependency management, easier to update, etc.
Update README to explain submodule initialization

To help transition users to the new way.
Switch to relative URL for submodule

This'll let people use whatever protocol (git, ssh, http, etc.) they
want when checking out the project and the submodule will automatically
use the same. See [this blog post][].

Fix build under Postgres 9.3

With the change to the `.SECONDARY` rule in [this commit][1], vanilla
Postgres extension builds do not keep intermediate files.

Rather than directly defining `all` and `clean` targets, we should be
following the [Postgres guidelines for making extensions][2] if at all
possible. This is as simple as defining special variables before in-
cluding the PGXS Makefile and making sure all relevant dependencies can
be built if needed.

Add Markdown suffix to `README`

For better markup capabilities.
Enhance `README` markup

Links, lists, headers, etc.
Update license information

We mean to use LGPLv3, not GPLv3. The former allows a shared library to
be linked from non-free software; the latter does not.

Also updated copyright declarations (first year of release through
current release year).
