An in-memory agnostic database for Python.
0.0.5
The Dataset.to_str() method now has the limit parameter to define the number of lines that should be displayed.
Added the Dataset.all() method to return all data, without applying any filters.
Added the format parameter in the add_field() method. This parameter is passed to the method of the Schema class and is used by it to define a format for the new field created.
Added date_format attribute to Dataset class. This attribute is used whenever values are entered in fields of type date or datetime to store the value in the intended format.
Validation of values at insertion time. Fields of type date or datetime, when receiving a value of type str, check the string format. If it's a valid date, it converts to the date format defined in the field (as an field attribute of the Schema object) or defined in the date_format attribute of the dataset.
Dataset now works as an iterator. Use foreach to loop through the lines.
Dataset now has a date_out_format property where we define the format in which date-type fields should display their values when converted to string.
Fixed the method that calculates the size of fields. Before I was calculating the size of the fields without considering the output formats when converting the fields to string.

There was an attempt to make the Dataset schemaless. But usage has shown that there is no advantage to using schemaless dataset.
Added private method Dataset.__set_schema() to set the schema in the dataset. If the method does not receive a schema, it takes care of instantiating one so that there is always a schema in the dataset.
