This data structure allows to quickly retrieve the state of a unit for a provided time
period. The value is either the default value of the unit or the value that the event
introduced. If the value in either BAT_DAY or BAT_HOUR is -1 it means that that specific
day or that specific hour are non-determinant. This means that in order to determine the
value of the event for that point in time we need to look at a lower level of granularity.
Example - consider breaking up the following event
start-date: 2016-01-01 1210
end-date: 2016-01-03 1210
value: 10
[BAT_DAY][2016][01][d1][-1] - The first day starts at 1210 so the DAY array is not enough
[BAT_DAY][2016][01][d2][10] - The second day is a full day at the same value of 10
[BAT_DAY][2016][01][d3][-1] - The last day is no a full day so the day array in non-determinant
[BAT_HOUR][2016][01][d1][h12][-1] - The first hour of the event starts at 10 minutes so the hour is non-determinant
[BAT_HOUR][2016][01][d1][h13][10]
[BAT_HOUR][2016][01][d1][h14][10]
[BAT_HOUR][2016][01][d1][h15][10]
[BAT_HOUR][2016][01][d1][h16][10]
[BAT_HOUR][2016][01][d1][h17][10]
[BAT_HOUR][2016][01][d1][h18][10]
[BAT_HOUR][2016][01][d1][h19][10]
[BAT_HOUR][2016][01][d1][h20][10]
[BAT_HOUR][2016][01][d1][h21][10]
[BAT_HOUR][2016][01][d1][h22][10]
[BAT_HOUR][2016][01][d1][h23][10]
- we don't need to state anything about hours on the 2nd of Jan since the day array is determinant
[BAT_HOUR][2016][01][d3][h01][10]
[BAT_HOUR][2016][01][d3][h02][10]
[BAT_HOUR][2016][01][d3][h03][10]

[BAT_HOUR][2016][01][d3][h08][10]
[BAT_HOUR][2016][01][d3][h09][10]
[BAT_HOUR][2016][01][d3][h10][10]
[BAT_HOUR][2016][01][d3][h11][10]
[BAT_HOUR][2016][01][d3][h12][-1] - The last hour of the event ends at the 10th minute so will need to minute array
[BAT_MINUTE][2016][01][d1][h12][m00][10] - Minutes, which is the maximum granularity, are always determinant
[BAT_MINUTE][2016][01][d1][h12][m01][10]
