Add property to indicate lengths of the dimensions to IValueSet

Wiki MarkupCurrently the text is for {{GetIndexCount(int\[\] indices)}} are:

/// <summary>
/// Returns the length (max index count) of the dimension specified by the
/// given indices. To get the size of the first dimension, use a zero-length
/// integer array as input argument. Length of indices must be a least one
/// smaller than the <see cref="NumberOfIndexes"/>
/// </summary>
/// <param name="indices">indexes of the dimension to get the length of</param>
/// <returns>length of the specified dimension</returns>

2.1.1. Slightly changed from 1.4 compliancy

The IBaseLinkableComponent is the key interface in the OpenMI standard version 2. Any OpenMI compliant component must implement IBaseLinkableComponent.
OpenMI-compliance definition:

1. An OpenMI-compliant component must implement the IBaseLinkableComponent interface according to specifications provided as comments in the OpenMI.Standard2 interface source code. *
2. An OpenMI-compliant component must, when compiled, reference the OpenMI.Standard2.dll, which is released and compiled by the OpenMI Association.
3. An OpenMI-compliant component must be associated with an XML file, which complies to (can be validated with) the BaseLinkableComponent.xsd schema (same information a 4. - leave it out?)
4. An OpenMI-compliant component must be associated with an XML file, which complies to (can be validated with) the OpenMICompliancyInfo.xsd schema. This file must be submitted to the OpenMI Association.
5. The OpenMI Association provides two additional interfaces that OpenMI-compliant components may or may not implement: the IManageState interface and the IByteStateConverter interface. However, if these interfaces are implemented, each method and property must be implemented according to the comments given in the OpenMI.Standard2 interface source code.
6. The OpenMI Association's downloadable standard zip file provides the only recognized version of source files, XML schemas and assembly files.

* at 1. The OpenMI Association provides extensions to the standard with more specific interfaces, e.g. for time and space dependent components. Although these extensions are part of the standard they are formally not required for compliancy. But the OpenMI Association recommends to implement the appropriate extension for easier data exchange with other OpenMI compliant components.
This means a change in the implementation of the classical time and space dependent component, which had in 1.x  just to implement the basic ILinkableComponent. For OpenMI 2 compliancy this component would have to implement the basic and the time and space specific extension interfaces.

2.1.2. Two level compliancy

...

The IBaseLinkableComponent is the key interface in the OpenMI standard version 2.

OpenMI-compliance definition:

1. An OpenMI-compliant component must implement the IBaseLinkableComponent interface according to the specifications provided as comments in the OpenMI.Standard2 interface source code.
2. An OpenMI extension-compliant component must implement the IBaseLinkableComponent interface and at least one of the extension interfaces according to the specifications provided as comments in the OpenMI.Standard2 interface source code. *
3. An OpenMI-compliant as well as an OpenMI extension-compliant component must, when compiled, reference the OpenMI.Standard2.dll, which is released and compiled by the OpenMI Association.
4. An OpenMI-compliant as well as an OpenMI extension-compliant component must be associated with an XML file, which complies to (can be validated with) the OpenMICompliancyInfo.xsd schema. This file must be submitted to the OpenMI Association.
5. The OpenMI Association provides two additional interfaces that OpenMI-compliant components may or may not implement: the IManageState interface and the IByteStateConverter interface. However, if these interfaces are implemented, each method and property must be implemented according to the comments given in the OpenMI.Standard2 interface source code.
6. The OpenMI Association's downloadable standard zip file provides the only recognized version of source files, XML schemas and assembly files.

* at 2.: This leads to a main difference between OpenMI 1.x and OpenMI 2. In order to become 1.x compliant the classical time and space dependent component just had to implement the basic ILinkableComponent. This component would have to implement the basic and the time and space specific extension interfaces for becoming OpenMI 2 compliant.

Decision : We choose for the second description, including the rephasing of Jesper
