It is not possible to store or retrieve an Int64

[st3fan]

The library currently does not support the Int64 type. It should be possible to store and retrieve Int64 values by wrapping them in an NSNumber.

I submitted a pull request to fix this issue: https://github.com/ryanfowler/SwiftData/pull/26

/**
Return the column value as an Int64
:returns:  An Optional Int64 corresponding to the apprioriate column value. Will be nil if: the column name does not exist, the value cannot be cast as a Int64, or the value is NULL
*/
public func asInt64() -> Int64?
{
    return value as? Int64
}
