Add pandas like methods that describe store content and structure. https://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.describe.html https://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.info.html The result of the methods is a JSON, they can be implemented in javascript.

// currently only JSON objects can be added store.push(record); // record is of type qm.Record support datetime objects in records - not pure JSON objects. Currently we need to transform...

Using casts uint64(-5.0) results in undefined behaviour, one was fixed in json.h, check if there are other cases.

Check for getters and setters that use pointer casts as they may not be portable on some devices. ARMv7 for example doesn't support unaligned access to doubles. See f6822404611d99153ce3907009ef89749a581ffa for...

-release + debug tests -code without warnings -code without tabs

base.search should work even if no keys are specified, by doing a linear search.

add support for time delayed feature extractors: `extractorDef = {recordOffset: [-1 0 1], ... }` will create a feature extractor that `featureExt` such that given `i`-th record it will extract...

Missing example, what it does and what the parameters mean.
