add global variable to configure datasets directory

[KoRiF]

this allows to load CIFAR10 & CIFAR100 datasets from the arbitrary location

by default, directory initialized as empty string, so this should not affects on the existing logic

usage:

`
...
uses neuraldatasets; //usual import
//initialization
neuraldatasets.directory := '..\..\Data\cifar-10-batches-bin'; // path to CIFAR-10* //including trailing path delimiter

`

The main idea is good. It's against my religion to have global variables. So, I'll implement your solution passing parameters.

in the place where the dataset is loaded, the religion is procedural programming style in a situation where there are no classes, using a global variable is not a religious crime. I mean, the module is called "neural dataset", and if it were a class, then the directory with the dataset could well be its field i.e. this global variable really defines the context, and is not a parameter of each new call to the algorithm therefore, probably, your gods would forgive us this sin 2021-10-27 16:32 GMT+03:00, joaopauloschuler ***@***.***>:

The request is valid and I'm still considering it.
