rldhont a0ffad2532 [FEATURE] Add get and transform geometry in Expression 
In version 2.6, new keywords has been added to Expression :
* $currentfeature - returns the current feature
* $atlasfeature - returns the atlas feature
* getFeature - gets a matching feature from a layer

But I think, Expression lacks a few keywords :
* geometry - returns the feature's geometry
* transform -  returns the transformed geometry

These new keywords can be used with getFeature for some geometry tests like
 intersects, crosses, contains, etc

Tests has been added to geometry and transform in Expression
