Pure Go implementation (#95)

Removes dependency on cgo and therefore no dependency on seabolt and gobolt.

Backwards compatible with 1.7 in all but one respect, neo4j server version must be 3.5 or higher. Only bolt protocol version 3 is currently supported.

 # neo4j-go-driver
 
-This is the the official Neo4j Go Driver. It is built on our C Connector, [seabolt](https://github.com/neo4j-drivers/seabolt) and depends on it to be available on the host system.
-
-##  Requirements
-
-This package requires the following tools/libraries to be installed in order to be built.
-
-1. C Compiler Toolchain  
-2. seabolt
-3. pkg-config tool for your platform
-
-## Requirements
-
-### Compiler Toolchain
-
-Install C/C++ compiler toolchain supported by your operating system. You'll need a mingw toolchain (for instance MSYS2 from https://www.msys2.org/) for cgo support (seabolt includes [instructions](https://github.com/neo4j-drivers/seabolt)) on Windows.
-
-### Pkg-Config
-
-Linux distributions provide `pkg-config` as part of their package management systems (`apt install pkg-config` or `yum install pkgconfig`).
-
-MacOS doesn't provide `pkg-config`, so have it installed through `brew install pkg-config`.
-
-Windows doesn't provide `pkg-config`, so have it installed by following [these instructions](https://stackoverflow.com/questions/1710922/how-to-install-pkg-config-in-windows?answertab=active#tab-top), make the `bin` folder available in PATH before any MSYS2 PATH entries. *This is mandatory because `pkg-config` that ships with MSYS2 has some path handling problems*
-
-### Seabolt
-
-[Seabolt](http://github.com/neo4j-drivers/seabolt) is the C Connector Library for Neo4j and is used by the Go driver as the base layer.
-Seabolt can either be installed from binaries or from source.
-
-#### Binaries
-
-We're provide _**experimental**_ binaries for `Linux`, `MacOS` and `Windows` [here](https://github.com/neo4j-drivers/seabolt/releases). Please remember that `OpenSSL` is a required dependency for `Linux` and `MacOS` - TLS on `Windows` depends on native SCHANNEL provider and doesn't require any additional third-party dependencies from version 1.7.3 onwards. 
-
-Download the binary matching your system and extract the package using the following command (assuming that you saved the package as ~/Downloads/seabolt.tar.gz).
-The command actually skips the top-level folder inside the tar.gz package and extracts its contents into the root folder `/`.:
-
-```
-tar zxvf ~/Downloads/seabolt.tar.gz --strip-components=1 -C /
-```
-
-#### Source
-
-Clone [seabolt](http://github.com/neo4j-drivers/seabolt) (assume `<seabolt_dir>` to be the absolute path in which the clone resides) and build it using one the provided `make_debug.[sh|cmd]` or `make_release.[sh|cmd]` scripts. The scripts set the installation path to `<seabolt_dir>/build/dist` and `<seabolt_install_dir>` in the following steps refer to it.
-
-Set `PKG_CONFIG_PATH` to `<seabolt_install_dir>/share/pkgconfig` on Linux/MacOS or to `<seabolt_install_dir>` on Windows.
-
-Set `LD_LIBRARY_PATH`/`DYLD_LIBRARY_PATH` to include `<seabolt_install_dir>/lib` on Linux/MacOS respectively. This is not necessary if you will link statically to seabolt or use `RPATH` feature on your platform (see below).
-
-Add `<seabolt_install_dir>\bin` to `PATH` environment variable on Windows.
-
-There's a 3rd party tap for [brew](https://brew.sh) that you can use to download, compile and install Seabolt into the correct place on macOS: [homebrew-seabolt/seabolt](https://github.com/michael-simons/homebrew-seabolt):
-
-```
-brew install michael-simons/homebrew-seabolt/seabolt
-```
+This is the the official Neo4j Go Driver.
 
 ## Getting the Driver
 
@@ -66,14 +12,6 @@ Add the driver as a dependency with `dep ensure -add github.com/neo4j/neo4j-go-d
 
 Add the driver with `go get github.com/neo4j/neo4j-go-driver/neo4j`
 
-## Static Linking
-
-We provide `seabolt_static` build tag to support static linking against seabolt and its dependencies. You can just pass `--tags seabolt_static` to your `go` toolset (like `go build --tags seabolt_static`) for your project and the generated binary will not have any runtime dependencies to `seabolt`.
-
-## Setting RPATH on Linux/MacOS
-
-Both Linux and MacOS dynamic loader support `RPATH` entries into executables so that they can locate their dependent shared libraries based on those entries. To have a `RUNPATH` entry to be added to your executable, you can pass `-ldflags "-r $(pkg-config --variable=libdir seabolt17)"` to your `go` toolset (like `go build -ldflags "-r $(pkg-config --variable=libdir seabolt17)"`) and it will add an `RPATH` entry to your executable that points to the location where seabolt shared library resides.
