Schedule - change type and rename

Created by: gioagu

Hello,

as discussed in Munich yesterday during the workshop, there are some requests regarding the schedules. The following proposals are from Giorgio, Thomas and Romain, but they were also (briefly) discussed with the other participants during the afternoon brainstorming.

Rename the exising schedules as follows:

ScheduleLoD0 --> ConstantValueSchedule
ScheduleLoD1 --> DualValueSchedule
ScheduleLoD2 --> DailyPatternSchedule
ScheduleLoD3 --> TimeSeriesSchedule

The reason is that using the LoDx naming leads to confusion. What is more, a schedule does not correspond to a specific LoD of a building.

As a schedule may be reused several times, the type should be changed from "DataType" to "FeatureType"
