predefined queries are subset of the generic Query class, covering all examples of the `ENTSO-E API guide <https://transparency.entsoe.eu/content/static_content/Static%20content/web%20api/Guide.html>`_.

    >>> predefined_query = ec.Queries.Balancing.AmountOfBalancingReservesUnderContract(

-----

| *ENTSO-E Client* enables straight-forward access to *all* of the data at `ENTSO-E Transparency Platform <https://transparency.entsoe.eu/>`_.

* Query templates abstract the API specifics through Enumerated types.

* Parse responses into Pandas DataFrames without loss of *any* information.

| The separation of Queries, Client and Parser with their hierarchical abstractions keep the package extensible and maintainable. A pipeline from Query to DataFrame is trivial, preserving the ability to customize steps in between.

| The implementation relies primarily on the
 `Transparency Platform restful API - user guide <https://transparency.entsoe.eu/content/static_content/Static%20content/web%20api/Guide.html>`_.
 The `Manual of Procedures (MoP) <https://www.entsoe.eu/data/transparency-platform/mop/>`_ documents provide
 further insight on the *business requirements specification*.
 Further information can be found in the
 `Electronic Data Interchange (EDI) Library <https://www.entsoe.eu/publications/electronic-data-interchange-edi-library/>`_.

-----

Main contributions

* Exhaustive List of ParameterTypes.
    These allow mapping between natural language and the codes required
    for GET requests, e.g. :code:`DocumentType.A85 == DocumentType("Imbalance price")`.
    This feature allows keeping track of queries without jumping between documents or adding comments.

* Exhaustive List of Pre-defined Queries from ENTSO-E API Guide.
    `ENTSO-E API Guide <https://transparency.entsoe.eu/content/static_content/Static%20content/web%20api/Guide.html>`_
    is a minial set for any API connector to implement and reflects all dashboards on
    ENTSO-E Transparency Platform.

* Parsers
    Response `Documents` come in XML schema which can be parsed into pandas DataFrames.

    Implemented: GL_MarketDocuments, TransmissionNetwork_MarketDocuments,
    Publication_MarketDocuments and Balancing_MarketDocuments.

    Missing: Outages, Congestion Management and System Operations.

Nevertheless, ENTSO-E Client seeks to be minimal to go from Query to DataFrame and requires domain-
knowledge on how to formulate queries and interpret various columns of a parsed response.

-----

ENTSO-E relies on many codes (`Type`) to map to desired queries.
Types are encoded in Enum classes with a .help() function to list the all.
They can be addressed through Type[code] or Type(string), making interaction
easy. HTTP requests and responses usually require the `code`, whereas we
want to formulate the query as a human-readable `string`.
