Facetapi Range

Facetapi widget, that allows users to enter minimum and maximum numeric values and filter results by range.

Use case: filter by price, by weight etc

Features:
- Custom prefix, suffix for both fields (translatable).
- Multiply, divide submitted values by any numeric factor you set in widget settings. Useful, for example, if facet keeps cents, but user entered amount in dollars
- Input validation - skip everything but numbers
- Live check if at least one field isn't empty, lock submit otherwise
- Supports "Up to or equal" or "Less than or equal" - just leave one field empty :)

*Some ideas were taken from great Facetapi Slider module
