Set method:
I thought of a method to change the the data. Something like:
myDb.set(varNameList, dataArray)
Extract method:
A way to get an other dbase object with a subset of variables.
Tomorrow I'll propose an implementation. Because your __init__ method
wants a file name it needs to be changed too.
GetAtTime:
Maybe your data are samples from some continuous process or function.
Then you might want to have values from between the stored
timepoints. You could compute them trough interpolation.
The following class from scipy will do the job:
