Bluetooth LE with GATT Profile Adjustments

[SvenEckhardt]

See #22: Adjust Generators and Model for the communication protocol. Necessary Adjustments are:

• [x] generate Methods stubs: Methods can be declared in the grammar in the following pattern: {+-#,~,-}name(ParameterType, parameter1, ParameterType, parameter2, ...):returnType. {+-#,~,-} has the same meaning as in UML. the visibility is optional without it the method will be public
• [x] generate Lists: Lists can be declared in the grammar in the following pattern: name as list as DataType. DataType is either the know DataTypes (UINT8, INT8, ...) or another DataSet that was declared by the user
• [x] use more datasets via "uses" (see #63)
• [x] make getter and setter excludable: getter and setter can be made excludeable by the keyworde exclude: followed by setter, getter

[SvenEckhardt]

These Changes are already made in the Meta model and in the Grammar. Furthermore the Java Genenerator was updated to fit these changes. The other generators (C, CSharp and JavaScript) still need to be updated to fit the Grammar changes

1. generate Methods stubs (DONE): In C the visibility of fields and methods is not defined. That is why the method stubs are defined without prefix.
2. generate Lists (PARTLY DONE): Since the C language does not provide support for dynamic lists by default, the length of the list could be defined explicitly in *.sidl file ( static list ) or a linked list could be implemented ( dynamic list ). In the second case, several extra functions have to be implemented for manipulation of the list. The functionality for the lists should be defined in order to implementd appriopriate functions.
3. use more datasets via "uses" (DONE): Multiple datasets have the same functionality as in Java generators.
4. make getter and setter excludable (DONE): Excludable getter/setter methods has now the same functionality as in Java generators.
