-- IgxInputGroup

+### General
+- `IgxInputGroup`
     - **Breaking Chage** - Removed `fluent`, `fluent_search`, `bootstrap`, and `indigo` as possible values for the `type` input property. 
     - **Behavioral Change** - The styling of the input group is now dictated by the theme being used. The remaining `types` - `line`, `border`, and `box` will only have effect on the styling when used with the `material` theme. The `search` type will affect styling when used with all themes. Changing the theme at runtime will not change the styling of the input group, a page refresh is required.
