Altaxo |
AltaxoVariant is the universal datatype used to return the value of a data column,
it is necessary because the type of the column can be text, date, or double
I decided to use struct which only holds the object because of its efficiency
AltaxoVariant is never used to store the data in the array, for this purpose
the native data types are used
