Azure Data Lake Store Filesystem Client Library

The `azure-datalake-store` library provides a pure-Python interface for Azure Data Lake Storage Gen 1, offering Pythonic file-system and file objects with capabilities for high-performance uploading and downloading. It is currently at version 1.0.1, having recently transitioned from a series of `0.0.x` pre-releases to a `1.0.x` stable branch. The project is under active development, but the official documentation notes it is 'not yet recommended for general use'. This library specifically supports ADLS Gen 1; for ADLS Gen 2, users should refer to `azure-storage-file-datalake`.
