Sample

## [v1.7.5g](https://github.com) (2019-06-22 15:55)

**Description:**
Minor patch fix in clustering

- Small changes to Clustering when no txns take place.
- Checks are now in place for nan(s) in sql insert statement.
- This was happening in the case of IH where no txns were taking place and hence elasticity was not calculable.
