feb3bee858 Add a bunch of optimised fuzzy string matching algorithms. 
A new QgsStringUtils class has been added containing some
common fuzzy matching algorithms, including Levenshtein edit
distance and Soundex. These can be used for finding "similar"
strings in a table.

Expression functions for these algorithms have also been
added to a new "Fuzzy Matching" group.

0af69ed9fb Add pertinent example for 'LIKE' operator 
The usage examples for the 'LIKE' operator are not really pertinent. The proposed change adds an example that actually illustrates the usual usage of the 'LIKE' operator.

96db1bdb7e Allow expression functions to include 0 length parameter lists 
This change allows for some cleanups to the built in expression
functions, by making it possible to differentiate variables
(eg $feature) from functions which don't require parameters
(eg uuid(), now()... ). Also adds aliases for uuid(), now(), and
pi().

bd9e02be95 Add alias support for expression functions 
Standardise naming of all internal functions to lowercase with
underscore convention. Add aliases for old names to avoid
breakage.

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
