        Initialized the OsmApi object.

        There are two different ways to authenticate a user.
        Either `username` and `password` are supplied directly or the path
        to a `passwordfile` is given, where on the first line username
        and password must be colon-separated (<user>:<pass>).

        To credit the application that supplies changes to OSM, an `appid`
        can be provided.  This is a string identifying the application.
        If this is omitted "osmapi" is used.

        It is possible to configure the URL to connect to using the `api`
        parameter.  By default this is the SSL version of the production API
        of OpenStreetMap, for testing purposes, one might prefer the official
        test instance at "api06.dev.openstreetmap.org" or any other valid
        OSM-API. To use an encrypted connection (HTTPS) simply add 'https://'
        in front of the hostname of the `api` parameter (e.g.
        https://api.openstreetmap.com).

        There are several options to control the changeset behaviour. By
        default, a programmer has to take care to open and close a changeset
        prior to make changes to OSM.
        By setting `changesetauto` to `True`, osmapi automatically opens
        changesets.
        The `changesetautotags` parameter takes a `dict`, where each key/value
        pair is applied as tags to the changeset.
        The option `changesetautosize` defines the size of each
        upload (default: 500) and `changesetautomulti` defines how many
        uploads should be made before closing a changeset and opening a new
        one (default: 1).

        The `session` parameter can be used to provide a custom requests
        http session object (requests.Session). This might be useful for
        OAuth authentication, custom adapters, hooks etc.

        Finally the `timeout` parameter is used by the http session to
        throw an expcetion if the the timeout (in seconds) has passed without
        an answer from the server.

        Initialized the OsmApi object.

        There are two different ways to authenticate a user.
        Either `username` and `password` are supplied directly or the path
        to a `passwordfile` is given, where on the first line username
        and password must be colon-separated (<user>:<pass>).

        To credit the application that supplies changes to OSM, an `appid`
        can be provided.  This is a string identifying the application.
        If this is omitted "osmapi" is used.

        It is possible to configure the URL to connect to using the `api`
        parameter.  By default this is the SSL version of the production API
        of OpenStreetMap, for testing purposes, one might prefer the official
        test instance at "api06.dev.openstreetmap.org" or any other valid
        OSM-API. To use an encrypted connection (HTTPS) simply add 'https://'
        in front of the hostname of the `api` parameter (e.g.
        https://api.openstreetmap.com).

        There are several options to control the changeset behaviour. By
        default, a programmer has to take care to open and close a changeset
        prior to make changes to OSM.
        By setting `changesetauto` to `True`, osmapi automatically opens
        changesets.
        The `changesetautotags` parameter takes a `dict`, where each key/value
        pair is applied as tags to the changeset.
        The option `changesetautosize` defines the size of each
        upload (default: 500) and `changesetautomulti` defines how many
        uploads should be made before closing a changeset and opening a new
        one (default: 1).

        The `session` parameter can be used to provide a custom requests
        http session object (requests.Session). This might be useful for
        OAuth authentication, custom adapters, hooks etc.

        Finally the `timeout` parameter is used by the http session to
        throw an expcetion if the the timeout (in seconds) has passed without
        an answer from the server.

        Initialized the OsmApi object.

        There are two different ways to authenticate a user.
        Either `username` and `password` are supplied directly or the path
        to a `passwordfile` is given, where on the first line username
        and password must be colon-separated (<user>:<pass>).

        To credit the application that supplies changes to OSM, an `appid`
        can be provided.  This is a string identifying the application.
        If this is omitted "osmapi" is used.

        It is possible to configure the URL to connect to using the `api`
        parameter.  By default this is the SSL version of the production API
        of OpenStreetMap, for testing purposes, one might prefer the official
        test instance at "api06.dev.openstreetmap.org" or any other valid
        OSM-API. To use an encrypted connection (HTTPS) simply add 'https://'
        in front of the hostname of the `api` parameter (e.g.
        https://api.openstreetmap.com).

        There are several options to control the changeset behaviour. By
        default, a programmer has to take care to open and close a changeset
        prior to make changes to OSM.
        By setting `changesetauto` to `True`, osmapi automatically opens
        changesets.
        The `changesetautotags` parameter takes a `dict`, where each key/value
        pair is applied as tags to the changeset.
        The option `changesetautosize` defines the size of each
        upload (default: 500) and `changesetautomulti` defines how many
        uploads should be made before closing a changeset and opening a new
        one (default: 1).

        The `session` parameter can be used to provide a custom requests
        http session object (requests.Session). This might be useful for
        OAuth authentication, custom adapters, hooks etc.

        Finally the `timeout` parameter is used by the http session to
        throw an expcetion if the the timeout (in seconds) has passed without
        an answer from the server.
