$parseProvider can be used for configuring the default behavior of the $parse
 service.
addLiteral(literalName, literalValue);
Configure $parse service to add literal values that will be present as literal at expressions.
| Param | Type | Details | 
|---|---|---|
| literalName | string | 
         Token for the literal value. The literal name value must be a valid literal name.  | 
    
| literalValue | * | 
         Value for this literal. All literal values must be primitives or   | 
    
setIdentifierFns([identifierStart], [identifierContinue]);
Allows defining the set of characters that are allowed in Angular expressions. The function
identifierStart will get called to know if a given character is a valid character to be the
first character for an identifier. The function identifierContinue will get called to know if
a given character is a valid character to be a follow-up identifier character. The functions
identifierStart and identifierContinue will receive as arguments the single character to be
identifier and the character code point. These arguments will be string and numeric. Keep in
mind that the string parameter can be two characters long depending on the character
representation. It is expected for the function to return true or false, whether that
character is allowed or not.
Since this function will be called extensivelly, keep the implementation of these functions fast, as the performance of these functions have a direct impact on the expressions parsing speed.
