Utility method used to read text fields from blob and fill item field set,Provides a mechanism to restore a
contact item field set from text blob field within contact database.
Blob informations are stored based on contact item field. At restore, a reference to a contact item field set
is provided. For every contact item field in the item field set, a text restore is made.
@param aFieldSet Reference to CContactItemFieldSet. Item field set that has to be filled with informations from blob
@param aHeaderStore Stream store containing the header informations
@param aId Root id for the header stream store
@param aValuesStore Read stream used to read text fields from text blob
@param aViewDef View definition indicating which fields have to be read from blob
@param aTemplate Template indicating if current field set should be filled based on a template
