Signature: AE.extract(attr, date1, date2=None, method='nearest', db='H')
Docstring:
Access function to perform extraction between date1 and date2.
Can extract one or several attributes.
date1 and date2 can be both exact date, or one of two can be a time interval that will be taken relative to the other.


Parameters:
-----------
attr: string, list, dict
    Attribute(s) to extract.
    If string, extract the given attribute, returning a pandas.Series.
    If list, extract attributes and return a list of pandas.Series.
    If a dict, extract attributes and return a dict of pandas.Series with same keys.

date1, date2: string, datetime.datetime, datetime.timedelta, None
    Exact date, or duration relative to date2.
    If string, it will be parsed.
    A start date can be given with string format '%Y-%m-%d-%H:%M:%S' or less precise (ie '2021-02', '2022-11-03' '2022-05-10-21:00'.i..).
    A duration can be given with string format 'Xu' where X is a number and u is a unit in ('m':minutes, 'h':hours, 'd':days, 'M':months)
    A datetime.datetime object or datetime.timedelta object will be used as is.
    date2 can be None. In that case it is replaced by the current time.

method: str
    Method of extraction
        'nearest': Retrieve nearest value of date1, date2 is ignored.
        'between': Retrive data between date1 and date2.

db: str
