 *   QGIS Programming conventions:
 *   
 *   mVariableName - a class level member variable
 *   sVariableName - a static class level member variable
 *   variableName() - accessor for a class member (no 'get' in front of name)
 *   setVariableName() - mutator for a class member (prefix with 'set')
 *
 *   Additional useful conventions:
 *
 *   theVariableName - a method parameter (prefix with 'the')
 *   myVariableName - a locally declared variable within a method ('my' prefix)
 * 
 *   DO: Use mixed case variable names - myVariableName
 *   DON'T: separate variable names using underscores: my_variable_name (NO!)
