Convert a hourly Ladybug data collection to a continuous collection at a specific timestep.

This will be done either through linear interpolation or by culling out values that do not fit the timestep. It can also be used to convert a discontinous data collection to a continuous one by linearly interpolating over holes in the data set.

### Inputs

* **data \[Required]**

A Ladybug Hourly DataCollection object. This can be either continuous or discontinuous.

* **timestep**

The timestep to which the data will be converted. If this is higher than the input \_data timestep, values will be linerarly interpolated to the new timestep. If it is lower, values that do not fit the timestep will be removed from the DataCollection. (Defaut: 1)

### Outputs

* **data**

A Continuous DataCollection at the input *timestep*.
