**functions.less**
- added convenience functions
- `fudge` fudge a number from 0-6 decimal places
- `unitless` simple hack to parse a number from a unit
**icons.less**
- removed explicit definitions in favor of a loop iterating `@fa-var-glyphs`
**mixins.less**
- removed requirement to pass `@rotation` to `@fa-icon-rotate`, it is now calculated
- calculation required since `@fa-rotation-increment` is configurable, meaning not every rotation may adhere to 90 degree increments requiring @rotation
**rotated-flipped.less**
- rotations are now calculated by a loop iterating `@fa-rotation-increment`
- the ie fix is now calculated using a loop iterating only the rotation selectors requiring intervention
- this is required now that `@fa-rotation-increment` eists
**sizes.less**
- sizes are now calculated by a loop iterating `@fa-var-scales`
- this new method supports the existing `.fa-lg` selector, as well as introducing: `.fa-xsm` (33%), `.fa-sm` (66%x), `.fa-default` (100%), `.fa-xlg` (166%)
- multipliers are now calculated by a loop iterating `@fa-var-multipliers`
- this new method supports all existing multipliers (`.fa-2x`, `.fa-3x`, `.fa-4x`, `.fa-5x`)
**variables.less**
- added variables:
- deprecated explicit icon variables in favor of an array value (`@fa-var-glyphs`)
- `@fa-rotation-increment`
- `@fa-var-scales`
- `@fa-var-multipliers`
**font-awesome.less**
- added `functions.less`
